# Delyn (UK Parliament constituency)

Delyn was a constituency in the House of Commons of the UK Parliament from 1983 to 2024.
The Delyn Senedd constituency was created with the same boundaries in 1999 (as an Assembly constituency).
The constituency was abolished as part of the 2023 Periodic Review of Westminster constituencies and under the June 2023 final recommendations of the Boundary Commission for Wales. Its wards were split between Alyn and Deeside, and Clwyd East.
It was last represented from 2019 to 2024 by Rob Roberts.

## Constituency profile

The seat comprised the mostly industrial Deeside communities of Mostyn, Flint, Mold, Northop and Holywell. Its residents were slightly less affluent than the UK average.

## Boundaries

1983–1997: The Borough of Delyn, and the Borough of Rhuddlan wards of Meliden, Prestatyn Central, Prestatyn East, Prestatyn North, and Prestatyn South West.

## History

The Delyn constituency was created in 1983 from the seats of Flintshire West and Flintshire East. It is normally inclined to elect Labour MPs, although the Conservatives won the seat in their 1983 and 1987 landslide elections, and regained it in 2019 when they won their biggest national majority since the 1980s. From 1983 to 1997, the constituency included Tory-leaning Prestatyn, which was then transferred to the Vale of Clwyd seat.
