A last-ditch attempt to preserve the present Brecon and Radnorshire parliamentary constituency is to be made in the House of Lords on Thursday by David Lipsey, a long-time resident of Tregoyd.

The government has proposed to make all constituencies have electorates within +/-5% of the national quota.

That would increase the size of the current Brecon and Radnorshire area from 55,000 to around 75,000.

Lord Lipsey, a Labour peer who lives at Tregoyd, has put down an amendment to the Parliamentary Constituencies Bill to keep the boundaries as they are now in the forthcoming boundary review.

Lord Lipsey said: “B and R is already a huge constituency. It takes an hour and a half to travel from North to South. It is also a very disparate constituency. Its large agricultural population is distinct in its concerns from the less rural south such as Ystradgynlais.

"Now under the government’s half-baked proposals a further 20,000 electors will be added.

"I tremble to think of the workload on the constituency’s current MP, Fay Jones, and her successors.

"The bill already allows for special constituencies to be exempt from the 5% rule that causes this problem. Ynys Mon is one beneficiary. Why can’t B and R be another?

"I have met with ministers who are so far refusing to change their proposals. Thursday’s debate in the Lords will provide a last chance to challenge this proposal.

“Save our Seat” will be our rallying cry.”
