The outgoing Unite leader tells the BBC he is pessimistic about Labour's chances at the next election.

Sharon Graham replaces Len McCluskey, and vows to focus on workers' rights rather than Westminster politics.

Sharon Graham looks set to take over from Len McCluskey to become the first woman to lead Unite.

The Unite boss warns Labour could "go under" if Sir Keir Starmer remains leader, in a new autobiography.

The three Left candidates to replace Len McCluskey become two, following behind-closed-door talks.

The left is divided over who should challenge Gerard Coyne to be the union's next general secretary.

Party leader Sir Keir Starmer must “reach out to the left”, the general secretary of the Unite union says.

The union - Labour's biggest donor - will begin voting on the replacement for Len McCluskey by July.
