As former Labour A-listers have called on Sir Keir Starmer to distance themselves from the European Convention on Human Rights (ECHR), Reform UK could swoop and turn red seats to turquoise.
Former Home Secretary Jack Straw, who oversaw the incorporation of the ECHR into British law, warned it was now being "misused" by British courts.
Straw, who served as the MP for Blackburn is now the third figure from the New Labour era to urge, following the Brexit-backing ex-Cabinet Minister Graham Stringer and former Home Secretary Lord Blunkett.
However, despite persistent calls from Reform UK leader Nigel Farage to leave the ECHR, the Prime Minister remains steadfastly against the suggestion.
A Downing Street spokesman said: "Let’s be clear: the ECHR underpins key international agreements on trade, security, migration and the Good Friday agreement.
"Anyone who is proposing to renegotiate the Good Friday agreement is not serious.
"We’re focused on the very serious policies to address this issue rather than a return to the gimmicks, the slogans, the chaos of the previous Government.”
Despite steadfast rejection from Downing Street, here are the Labour seats where a 2024 study by Onward found there the highest support for reducing migration.

The Cumbria seat was newly created for the 2024 General Election from the Copeland and Workington constituencies.
Labour's Josh MacAlister won the brand new seat, beating Reform UK's David Surtees with a majority of 13,286.
Conservative candidate Andrew Johnson came in third, with Green Party candidate Jill Perry in fourth.
In a post on social media in February, Mr MacAlister said: "Labour is taking action to boost our border security and ensure that immigration rules are respected and properly enforced.
"In Parliament yesterday I voted for Labour’s Asylum and Immigration Bill, which introduces new counter-terror style powers to go after the dangerous smuggler and trafficking gangs who organise small boats, undermining our border security and putting lives at risk."
In the 2016 European Referendum, 62 per cent of the Copeland Council voted to leave the EU.

The former Tory MP for the constituency, Dehenna Davison has been a vocal defender of Brexit, but admitted it could have been ‘done’ better.
She said: "Brexit was never just about numbers on the side of the bus or anything like that. It was about British people having authority over modern Britain. The concept of Brexit was absolutely the right thing to do."
The constituency voted decisively to leave the European Union with 60.89 percent backing Brexit.
At this year's local elections, where County Durham came under Reform UK's control for the first time, Nigel Farage's party won two out of the five Bishop Auckland wards.
