RHYL could be sliced in half under new proposals to cut the number of Welsh constituencies.
A paper released last week outlined proposals to carve up Clwyd West and the Vale of Clwyd to balance out the number of voters in each electoral zone, leaving Rhyl on two sides of the divide.
Chris Ruane, MP for the Vale of Clwyd, blasted the move as “unnecessary”.
He said: “These plans have always been about reducing Wales's voice and influence at Westminster. We opposed the plans on this basis, and continues to do so.
“It’s a bad news day for Wales. If these proposals go through, we will lose 25% of our seats. It’s bad news for North Wales, as of those 10 seats, four are in the North.”
The proposals are to merge part of the Vale of Clwyd, which covers Rhyl and Prestatyn, with Delyn which covers Flintshire, to create the Dee Estuary constituency.
St Asaph and half of Rhyl will be shuffled into the new North Wales Coast constituency, which covers Abergele to Conwy.
Mr Ruane said: “It’s bad news for the Vale of Clwyd because we will be sliced in two. It’s an unnecessary upheaval. Westminster say it’s to get a more equal electorate for the seats, but if they feel that strongly, they should consider those people not registered to vote.”
Mr Ruane said that if the estimated 8.5 million non-registered Welsh residents were encouraged to register, the inequalities in the number of voters would even out, and give the more marginalised in society a voice.
The report released by the Boundary Commission stated: “The commission’s initial proposals would, if adopted, result in a parliamentary map of Wales very different to that with which we are familiar.
“The commission has, at every stage of its deliberations, sought to identify the solutions most suitable for local needs through Wales.”
