# Mid Derbyshire (UK Parliament constituency)

Mid Derbyshire is a constituency represented in the House of Commons of the UK Parliament. The Member of Parliament has been Jonathan Davies of the Labour Party since the 2024 United Kingdom general election. As with all constituencies, the constituency elects one Member of Parliament (MP) by the first past the post system of election at least every five years.
The previous MP was Pauline Latham, a Conservative, from 2010 until she stood down in 2024.

## Constituency profile

The constituency covers a large area to the north and east of Derby. Residents are slightly wealthier than the UK average.

## Boundaries
### 2010–2024

Following their review of parliamentary representation, the Boundary Commission for England created this seat for the 2010 general election. Neighbouring constituencies had consequential boundary changes, with Erewash and Amber Valley the most affected.
The constituency was made up of the following electoral wards:
* Belper Central; Belper East; Belper North; Belper South; Duffield, part of the borough of Amber Valley
* Allestree, Oakwood and Spondon, part of the City of Derby
* Little Eaton and Breadsall; Ockbrook and Borrowash; Stanley; West Hallam and Dale Abbey, part of the borough of Erewash$^1$
$^1$ Further to a local government boundary review in Erewash which became effective in May 2015, the Stanley ward was merged into Little Eaton and Breadsall which was renamed Little Eaton and Stanley.

### Current

Following the 2023 Periodic Review of Westminster constituencies, which came into effect for the 2024 general election, the constituency was expanded by adding the South West Parishes ward in the Borough of Amber Valley (as it existed on 1 December 2020), transferred from Derbyshire Dales.
Following local government boundary reviews in Amber Valley and Derby which came into effect in May 2023, the constituency now comprises the following:
* The Borough of Amber Valley wards of: Alport & South West Parishes (part); Belper East; Belper North; Belper South; Duffield & Quarndon.
* The City of Derby wards of: Allestree; Chaddesden North (small part); Oakwood (most); Spondon.
* The Borough of Erewash wards of: Little Eaton & Stanley; Ockbrook & Borrowash; West Hallam & Dale Abbey.
