These are the North Wales constituencies after shake-up of boundaries

All Welsh seats, except Ynys Môn, have been affected.

These significant changes to Westminster seats in Wales will radically affect the upcoming General Election when we go to the polls next month.

One of the new constituencies in Bangor Aberconwy, which will be contested by eight election candidates on July 4.

The newly created constituency incorporates the old Arfon, which makes up 40.9% of the new area, and the old Aberconwy district.

The Arfon seat is currently held by Plaid Cymru MP Hywel Williams, who is stepping down, whilst the Aberconwy seat was held by Conservative MP Robin Millar, who is again in contention.

In Denbighshire, the main constituencies are Clwyd North and Clwyd East.

This means that voters living in Rhyl are now in Clwyd North, the same as Colwyn Bay, while neighbouring Prestatyn lies in Clwyd East.

Why have the constituencies changed?

Shereen Williams MBE, secretary to the Boundary Commission for Wales, said: “It is our firm belief that these recommendations represent the best way to create 32 constituencies in Wales which meet the requirements of the act, including taking account of geography and local ties.

“Though managing a significant reduction in the number of constituencies is never an easy task for a Boundary Commission, it has been made significantly easier thanks to the number and quality of representations we have received from the public, from MPs, from political parties, and from principal councils across Wales.

“The Commission would like to put on record its thanks to everyone who took part in the review and strengthened the recommendations.”
