Voters in Westminster North will be left “without a voice” if proposals to carve up the constituency get the green light, MP Karen Buck has warned.

The wards making up Ms Buck’s constituency of Westminster North could be split between three seats in a nationwide shake-up announced by the Boundary Commission.

She said: “I think it’s a disaster. The representation for the area will be split three ways and people in Westminster North will lose their voice in Parliament.

“The Conservative Party will win out of this, because it splits the Labour vote.

“But the top line in all this is the people of North Westminster, whether they vote Labour or Conservative, will not have anyone who speaks for their interests.”

The constituency would be largely split between two new seats under the proposals.

Westbourne, Bayswater, Lancaster Gate, Bryanston and Dorset Square and Marylebone High Street would form part of Cities of London and Westminster.

Maida Vale, Abbey Road, Regent’s Park, Church Street and Little Venice would become part of Camden and Regent’s Park, while Queen’s Park and Harrow Road would become part of the Kensington constituency.

Previous proposals published in September suggested creating a Paddington constituency, with a much closer resemblance to the current boundary.

The Westminster North seat was originally abolished in 1997, then re-created for the 2010 General Election.

In the 2001 and 2005 elections, the area was split between two seats along similar boundaries to those currently proposed.

The public have until December 10 to comment on the proposals, before they go to Parliament next October.

Liberal Democrat MPs have indicated they will vote against the proposals.

Ms Buck added: “We will sit down and look at the proposals in detail. I expect them to be defeated.”
