MPS have backed calls for Parliament to get an earlier chance to vote on proposed changes to constituency boundaries that would see 50 fewer seats in the House of Commons.

The Public Administration and Constitutional Affairs Committee (PACAC) has called for MPs to be able to vote on whether to carry on with the current boundary review or begin a fresh review in time for the next general election, which could be in 2022.

Brighton and Hove MPs have since shown support for the vote to be brought forward so they don’t have to wait until the current review is finished in September to debate the issue.

Peter Kyle, MP for Hove, said: “Everyone agrees that a boundary review is needed, but it needs to be one that benefits democracy and not just the Tory Party.

“I therefore welcome the involvement of Parliament so that we can have a full and robust debate on the matter.

“A debate in Parliament would also allow me to make the case for officially having Portslade in the constituency name.”

Proposals within the present boundary review include reducing the number of MPs sitting in the Commons from 650 to 600.

The PACAC has recommended they be given the chance to vote on whether the number of MPs should remain at 650 as part of a new review in time for the election.

A report published by the cross-party committee this week concluded that MPs are not likely to support the current proposals to reduce the number of constituencies.

It also suggested if the vote is not carried out before September, there might not be enough time for a new review to be held before the next election if new legislation needs to be made.

Caroline Lucas, Brighton Pavilion MP, said it is “nonsense” to suggest reducing the number of MPs should be put first when it comes to strengthening democracy.

Ms Lucas said: “We have an electoral system that systematically locks people out of the democratic process, and produces deeply skewed results.

“We also have a second chamber which is entirely unelected – and extremely unrepresentative of modern Britain.

“The Government should focus on the real issues when it comes to accountability in British politics – not reduce the number of MPs and risk making them even less accountable to the electorate.”

Under the current proposals, which were announced last October, Brighton Pavilion would lose Regency ward to Hove, which as a constituency would be known as Hove and Regency.

Brighton Pavilion would be cut off from the sea if the proposals are approved but it would also include Moulsecoomb and Bevendean wards.

Chairman of the PACAC Bernard Jenkin said: “The time to decide this in principle is now.

“If the Government waits until the autumn, Parliament will be faced with an invidious choice: either approve the new boundaries or hold the next election on boundaries that will be over 20 years out of date.”
