PROPOSED changes to reduce the number of MPs will leave one at risk of losing his seat to the Tories.

Labour’s Lloyd Russell-Moyle won his Brighton Kemptown seat in 2017, but the changes, described as “gerrymandering”, would see Conservative-leaning Newhaven and Seaford fall within his constituency and put his seat at risk.

Mr Russell-Moyle called the changes, which would also see Brighton’s St James’s Street split into two, “a great folly”.

He said: “My seat is going to becoming a super marginal seat so there’s all to fight for and I will put up a big fight. But if this goes through I will relish the opportunity to stand and win in Newhaven and Seaford.”

Currently, Mr Russell-Moyle’s seat encompasses the area between the Western end of St James’s Street, Brighton, to the eastern edge of Peacehaven.

He said the new map was poorly drawn and argued that services for his new constituents would not fall within his constituency.

He said: “If you get pregnant or break a leg in Seaford you use Eastbourne hospital.

“If you need council housing, you will be paying the Eastbourne rate. If you are going to sixth form college you will probably go to Eastbourne.”

Labour MP for Hove and Portslade Peter Kyle has denounced the plans as gerrymandering.

Mr Kyle’s Hove seat remains largely unchanged, but he would gain part of the seafront on the western side of Brighton Palace Pier.

Mr Kyle said: “I think the boundary changes are gerrymandering.

“By reducing MPs they are diminishing the ability of representatives to criticise Parliament and it skews the balance of electoral success towards the Conservative Party.”

The proposals would cut the current 650 MPs down to 600 by redrawing constituency boundaries.

Caroline Lucas, the Green MP party for Brighton Pavilion, would still represent part of the city’s seafront.

She told The Argus that the changes were “misguided” and the Government should stop “fiddling with constituencies”.

She added: “We shouldn’t be reducing the total number of MPs.

“Our workload is already increasing and cutting numbers would also mean even less accountability for the Government.”

The plans are the result of two years of complex consultation and would broadly benefit the Conservatives.

If the proposals were applied to the 2017 election, the Conservatives would have won overall control.

However, prominent politicians including Boris Johnson and David Davis could find their seats under threat.
