He said: “I have been elected as the Labour MP for Islington North on 10 consecutive occasions since 1983. I am proud to represent a community that supports vulnerable people, joins workers on the picket line and fights for transformative change.

“Our message is clear: we are not going anywhere. Neither is our determination to stand up for a better world.”
