# Windsor (UK Parliament constituency)

Windsor (/ˈwɪnzə/) is a constituency of the House of Commons in the UK Parliament represented since 2024 by Jack Rankin of the Conservative Party. It was re-created for the 1997 general election after it was abolished following the 1970 general election and replaced by the Windsor and Maidenhead constituency.

## Constituency profile

The constituency is centred on Windsor Great Park, covering the eponymous town of Windsor and various towns and villages in RBWM and Slough, in Berkshire, and Runnymede in Surrey.
The re-created constituency, from 1997, has continued a trend of large Conservative Party majorities. Post 2023 boundary changes, in local elections in the seat the major opposition party varies, with Labour strong in the Slough wards and Englefield Green, the Liberal Democrats in the town of Windsor itself, and independents in various villages. That said, affluent villages and small towns along the River Thames and around the Great Park have continued to contribute to large Conservative majorities, including Wraysbury and Ascot.
In the 2024 General Election, Labour came second to the Conservatives due to the changed composition of the seat in the boundary changes.

## History

Windsor has had parliamentary representation for centuries, formally known as the Parliamentary Borough of New Windsor, first sending a member in 1301, and continuously from 1424. It elected two members of parliament until 1868, when its representation was reduced to one MP. In 1918, the Parliamentary Borough was abolished and absorbed into the new county seat of Windsor, which also included large parts of the abolished Wokingham constituency.
In 1974, the constituency was abolished and replaced by Windsor and Maidenhead, although there were no changes to the boundaries. In 1997, the constituency was recreated when Windsor and Maidenhead was split into two separate seats.
The early political history of the area was strongly influenced by the monarch and members of his or her family. Windsor Castle has been an important royal residence throughout the history of the constituency.

### 17th century

The pre-1832 franchise of the borough was held by inhabitants paying scot and lot (a local tax). On 2 May 1689 the House of Commons had decided that the electorate should be limited to the members of Windsor Corporation. This was disputed after the next election, in 1690, when the Mayor submitted two returns of different members. The House of Commons reversed the decision of the previous Parliament and confirmed the scot and lot franchise.

### 18th century

There were 278 electors in 1712. Namier and Brooke estimated that, in 1754–1790, there were about 300 electors.
During part of the 18th century the Duke of Cumberland (son of King George II) and the Beauclerk family (descended from King Charles II) had political interests in the borough.
King George III became personally involved in the hotly contested 1780 general election. George encouraged local landowner Peniston Portlock Powney to stand by paying him £2,500 from the King's personal account. The King wished to defeat Admiral Keppel (later Viscount Keppel), an incumbent. The monarch went so far as to canvass tradesmen who dealt with the royal household. After this royal interference in the election, Keppel lost by a narrow 16 votes. Namier and Brooke suggest the Windsor electorate had an independent streak and were difficult to manage.

### 19th century

In 1832 a new property based franchise replaced the scot and lot qualification. Under the new system, there were 507 registered electors in 1832. The borough representatives before the Reform Act 1832 included soldiers and people connected with the Royal Household, such as Sir Richard Hussey Vivian (MP 1826–1831) and Sir Herbert Taylor (MP 1820–1823). The constituency also returned politicians prominent in national politics, like the Duke of Wellington's elder brother the Earl of Mornington in the 1780s and 1790s or the future Prime Minister Edward Stanley (subsequently the Earl of Derby) in the early 1830s).
The Ramsbottom family filled one seat from 1806 until 1845. The borough had been loyal to the King's Pittite/Tory ministers in the late 18th and early 19th centuries, but became more favourable to the Whig interest after John Ramsbottom (MP 1810–1845) was elected.
By the 1860s the monarch had ceased to interfere in local affairs. The borough fell under the patronage of Colonel R. Richardson-Gardner. Richardson-Gardner was a local landowner, who caused some animosity when following the 1868 general election he evicted tenants who did not support him at the polls. This was the last Parliamentary election the Conservatives lost in Windsor.
Despite (or perhaps because of) his methods, Richardson-Gardner was elected to Parliament in 1874.

### 20th century

Successive Conservative MPs, before the First World War, had considerable influence in the constituency; especially when they subscribed generously to local institutions such as a hospital.
The county division created in 1918 combined the town of Windsor, with territory to its west, south and east which had formerly been in the Wokingham division. The incumbent MP for Wokingham up to 1918, Ernest Gardner, was the first representative of the expanded Windsor constituency. The Conservative Party retained the seat continuously until its temporary abolition in 1974, as it has since its recreation in 1997.

## Boundaries and boundary changes
### Before 1868

The parliamentary borough of New Windsor was based upon the easternmost town in Berkshire in South East England, which grew up around Windsor Castle and the narrowly defined electorate could also vote for the county representatives. The north boundary of the constituency was on the River Thames, which was then the border between Buckinghamshire which had a seat of the same name and Berkshire, likewise the rest of the borough adjoined the Berkshire county constituency.

### 1868–1918

The boundaries of the parliamentary borough were extended by the Parliamentary Boundaries Act 1868 (31 & 32 Vict., c. 46) to include the villages of Clewer and Eton (the latter then being in Buckinghamshire, north of the Thames).
Between 1885 and 1918 the seat to the north of the Thames was the Wycombe division of Buckinghamshire and the other neighbouring constituency was the Wokingham division of Berkshire.

### 1918–1950

The parliamentary borough was abolished by the Representation of the People Act 1918 and replaced by a county division named Windsor. The constituency comprised the local government areas (as they existed in 1918):
* The Municipal Boroughs of New Windsor and Maidenhead;
* the Rural Districts of Cookham, Easthampstead and Windsor; and
* Part of the Rural District of Wokingham.
The new constituency comprised the bulk of the abolished Wokingham division, including Maidenhead and rural areas surrounding Windsor and Maidenhead, but excluding the Municipal Borough of Wokingham itself, and incorporating the abolished Borough, with the exception of Eton, which was added to the Wycombe division of Buckinghamshire.

### 1950–1974

The constituency was reduced in size by the Representation of the People Act 1948, comprising:
* the Municipal Boroughs of New Windsor and Maidenhead; and
* the Rural Districts of Cookham and Windsor.
The Rural District of Easthampstead (which incorporated Bracknell) and the part of the Rural District of Wokingham were transferred to the re-established constituency of Wokingham.
For the February 1974 general election, the constituency was abolished and renamed Windsor and Maidenhead, with no changes to its boundaries; this area plus Eton, which was transferred from Buckinghamshire, became the Royal Borough of Windsor and Maidenhead established under the Local Government Act 1972.

### 1997–2010

For the 1997 general election, in order to effect an increase in Berkshire's representation from 7 to 8 MPs in accordance with the Fourth Periodic Review of Westminster Constituencies, the Windsor and Maidenhead constituency was abolished and two separate constituencies of Maidenhead and Windsor were created. The composition of the new constituency was:-
* The Borough of Bracknell Forest wards of Ascot, Cranbourne, and St Mary's;
* The Borough of Slough ward of Foxborough; and
* The Borough of Windsor and Maidenhead wards of Bray, Castle, Clewer North, Clewer South, Datchet, Eton North and South, Eton West, Horton and Wraysbury, Old Windsor, Park, Sunningdale and South Ascot, Sunninghill, and Trinity.
The majority of the electorate in the abolished constituency was included in Maidenhead, whilst Windsor was joined by Eton and Bray. It also included a ward of Slough Borough Council north of the Thames, which was transferred from the Borough Constituency of Slough, and was extended southwards to include a part of the abolished constituency of East Berkshire, including Ascot and Sunningdale.
In 1998 there was a small re-alignment of county boundaries in the north east corner of Berkshire. This transferred to the Borough of Slough a small polling district from Surrey and another from Buckinghamshire to form Colnbrook and Poyle. This new ward (since renamed Colnbrook with Poyle) was added to the Windsor constituency and was effective from the 2001 general election.

### 2010–2024

Further to the Fifth Periodic Review, the composition of the constituency is:-
* The Borough of Bracknell Forest wards of Ascot, Binfield with Warfield, Warfield Harvest Rise, and Winkfield and Cranbourne;
* The Borough of Slough ward of Colnbrook with Poyle; and
* The Borough of Windsor and Maidenhead wards of Ascot and Cheapside, Castle Without, Clewer East, Clewer North, Clewer South, Datchet, Eton and Castle, Eton Wick, Horton and Wraysbury, Old Windsor, Park, Sunningdale, Sunninghill and South Ascot.
The constituency gained the northern part of the constituency of Bracknell, including Binfield. Bray was transferred to Maidenhead and the Foxborough ward of the Borough of Slough returned to the Borough Constituency thereof.

### 2024–present

Further to the 2023 Periodic Review of Westminster constituencies which became effective for the 2024 general election, the constituency is composed of the following (as they existed on 1 December 2020):
* The Borough of Runnymede wards of: Englefield Green East; Englefield Green West; Virginia Water.
* The Borough of Slough wards of: Colnbrook with Poyle; Foxborough; Langley Kedermister.$^1$
* The Royal Borough of Windsor and Maidenhead wards of: Ascot & Sunninghill; Clewer & Dedworth East; Clewer & Dedworth West; Clewer East; Datchet, Horton & Wraysbury; Eton & Castle; Old Windsor; Sunningdale & Cheapside.
The seat was expanded by adding two Borough of Slough wards from the Slough constituency and the communities of Englefield Green and Virginia Water from the Surrey constituency of Runnymede and Weybridge, thus creating a cross-county boundary seat. To compensate, the Bracknell Forest wards were transferred to Maidenhead, except the Warfield Harvest Ride ward, which went to Bracknell.
$^1$ Following a local government boundary review which came into effect in May 2023, the parts in the Borough of Slough will now comprise the following wards from the 2024 general election:
* Colnbrook & Poyle; Langley Foxborough; Langley Marish (most); Langley St Mary's (small part).

### Elections 1868–1880

The bloc vote electoral system was used in two seat elections and first past the post for single member by-elections and general elections from 1868. Each voter had up to as many votes as there were seats to be filled. Votes had to be cast by a spoken declaration, in public, at the hustings (until the secret ballot was introduced in 1872).

### Elections 1690–1866

Note on percentage change calculations: Where there was only one candidate of a party in successive elections, for the same number of seats, change is calculated on the party percentage vote. Where there was more than one candidate, in one or both successive elections for the same number of seats, then change is calculated on the individual percentage vote.
Note on sources: The information for the election results given below is taken from Cruickshanks et al. 1690–1715, Sedgwick 1715–1754, Namier and Brooke 1754–1790, Stooks Smith 1790–1832 and from Craig thereafter. Where Stooks Smith gives additional information or differs from the other sources this is indicated in a note after the result. When a candidate is described as Non Partisan for an election this means that the sources used do not give a party label. This does not necessarily mean that the candidate did not regard himself as a member of a party or acted as such in Parliament. Craig's party labels have been varied to take account of the development of parties. Tory candidates are classified as Conservative from the 1835 United Kingdom general election. Whig and Radical candidates are classified separately until the formal establishment of the Liberal Party shortly after the 1859 United Kingdom general election.
