The Boundary Commission has released the proposed changes to Parliamentary seats which reduce the number of MP's by 50 and try and make all constitutencies of similar size (no fewer than 71,031 and no more than 78,507 electors). The first draft details were released on the 13th September.
Most of E14 was in the Poplar & Limehouse constituency with Jim Fitzpatrick as MP (he is retiring though at the next election).
Most of Poplar & Limehouse stays the same but adds Whitechapel, Stepney Green & St Dunstands wards from the central part of Tower Hamlets
But it loses Lansbury ward, Bromley North & South to a new Bow & Canning Town constituency which include parts of Newham. The parliamentary boundaries no longer cover exactly the borders of Tower Hamlets but do follow the ward boundaries implemented in 2014.
That means the E14 postcode (roughly this group) will be split between two parliamentary constituencies in future, Poplar & Limehouse and Bow & Canning Town. The voting population of 74,863 is about average but as new developments are completed & the population goes up the old problem will re-emerge, the vote of people in E14 will be worth less then seats which are not growing.
You have six weeks to respond to the consultation as this is only a first draft. The changes will be finalised over the next two years.
