Hampstead and part of Highgate could be re-united if new political boundaries are introduced next year.

Camden’s Highgate ward, which is at the moment part of Holborn and St Pancras constituency, would fall under Hampstead and Kilburn under revised plans to alter constituency boundaries published by the Boundary Commission on Tuesday.

Belsize and Fortune Green wards will also remain part of Hampstead and Kilburn after a back track on original plans to move the wards to neighbouring constituencies.

The changes are proposed under a Conservative policy to redraw constituency boundaries and reduce the number of MPs. Final recommendations will be made in October next year.

But deputy prime minister Nick Clegg has told his party to vote against the bill after his coalition partners blocked Liberal Democrat efforts to reform the House of Lords.

Camden Conservatives welcomed the revised proposals as a victory for local campaigners - who mounted one of the largest opposition bids in the country to the original boundary change plans.

Cllr Andrew Mennear, leader of Camden Conservatives, said: “This is what Camden residents wanted and we were happy that the Conservative Party put forward amendments like these.

“Overall, this was a result that will please most people in Camden, should the boundary changes still go ahead.”

Camden Lib Dem leader, Cllr Keith Moffitt, added: “I’m delighted that common sense has prevailed so that Fortune Green is no longer separated from its twin sister West Hampstead, and similarly that Belsize is also back in Hampstead and Kilburn.”

But Glenda Jackson, Labour MP for Hampstead and Kilburn, said: “I have always believed the changes are gerrymandering to the Conservatives. It will be very interesting to see what happens.”
