The borders of Tower Hamlets’ parliamentary constituencies will not change despite a planned shake up for the rest of London.

Bethnal Green and Bow, the seat currently held by Rushanara Ali, and Poplar and Limehouse, which Jim Fitzpatrick holds, will remain as they are in the 2013 plans.

In the capital overall, the number of constituencies will be reduced from 73 to 68.

Only four, including the two East End seats, will remain unchanged.

David Cameron vowed to reduce the number of MPs before the Tories took power last year.

As part of the shake-up, 31 constituencies will be axed across England, leaving 502.

The Boundary Commission for England today announced it is consulting over the plans.

It said the changes are being brought in to make sure each constituency has a similar number of registered electors – between 72,810 and 80,473.

Simon James, secretary to the commission, said: “Parliament has set clear rules on what we can and can’t do when it comes to developing our initial proposals – BCE was given clear principles.”
