Labour leader Jeremy Corbyn today promised to fight plans to abolish his Islington North constituency of 33 years.

In order to reduce the number of MPs from 650 to 600, the Boundary Commission for England intends to merge five wards from Mr Corbyn’s seat into a new Finsbury Park and Stoke Newington constituency.

Islington North has existed since 1885, and Mr Corbyn told the Gazette this morning: “It’s very sad that Islington North, which has existed for a very long time, would disappear in name altogether. I find it sad from a historical and community point of view.”

The proposed boundaries were re-drawn based on registered voters as of December last year, rather than actual populations. Since then, two million nationwide have registered.

And Mr Corbyn echoed colleague Emily Thornberry, MP for Islington South and Finsbury, who branded the changes “profoundly wrong”.

“We are looking at the consultation [which runs until December 5] and all methods of appeal,” Mr Corbyn said.

“I am deeply concerned the commission was working on incorrect information about the electorate.

“People who are newly registered would still be able to vote, of course, but they would be under-represented if this goes ahead.”

Under the proposals, each parliamentary seat would have between 71,031 and 78,507 electors. In figures used by the commission, Islington North had 69,208 last year. Islington South and Finsbury had 64,929.
