# Alyn and Deeside (UK Parliament constituency)

Alyn and Deeside (Welsh: Alun a Glannau Dyfrdwy) is a parliamentary constituency represented in the House of Commons of the Parliament of the United Kingdom (at Westminster) since 2001 by Mark Tami of the Labour Party. The constituency was created in 1983, and it elects one Member of Parliament (MP) by the first-past-the-post method of election.
The Alyn and Deeside Senedd constituency was created with the same boundaries in 1999.
The constituency retained its name and gained wards, as part of the 2023 review of Westminster constituencies of the Boundary Commission for Wales for the 2024 general election.

## Boundaries

1983–1997: The District of Alyn and Deeside, and the Borough of Wrexham Maelor wards 13 and 14.
1997–2010: The District of Alyn and Deeside.

2024–present: From the 2024 general election the seat of Alyn and Deeside was expanded towards Flint as a result of the abolition of the Delyn constituency in the 2023 review of Westminster constituencies.

* Aston, Bagillt East, Bagillt West, Broughton North East, Broughton South, Buckley Bistre East, Buckley Bistre West, Buckley Mountain, Buckley Pentrobin, Caergwrle, Connah’s Quay Central, Connah’s Quay Golftyn, Connah's Quay South, Connah's Quay Wepre, Ewloe, Flint Castle, Flint Coleshill, Flint Oakenholt, Flint Trelawny, Hawarden, Higher Kinnerton, Hope, Llanfynydd, Mancot, Penyffordd, Queensferry, Saltney Mold Junction, Saltney Stonebridge, Sealand, Shotton East, Shotton Higher, Shotton West, and Treuddyn.
Following a local government boundary review which came into effect in May 2022, the constituency now comprises the following wards of the County of Flintshire from the 2024 general election:
* Bagillt, Broughton North East, Broughton South, Buckley: Bistre East, Buckley: Bistre West, Buckley: Mountain, Buckley: Pentrobin, Caergwrle, Connah’s Quay Central, Connah’s Quay: Golftyn, Connah's Quay South, Connah's Quay: Wepre, Flint: Castle, Flint: Coleshill and Trelawney, Flint: Oakenholt, Hawarden: Aston, Hawarden: Ewloe, Hawarden: Mancot, Higher Kinnerton, Hope, Llanfynydd, Pen-y-ffordd, Queensferry and Sealand, Saltney Ferry, Shotton East and Shotton Higher, Shotton West, and Treuddyn.
