Jon Trickett announces support for Rebecca Long-Bailey in Labour leadership contest

Ms Long-Bailey is on the left wing of the party and has the backing of the current Corbyn administration, as well political organisation Momentum and trade union Unite.

Her critics have referred to her as the “Corbyn continuity candidate”.

In a tweet, Mr Trickett said: "I am voting RLB for leader. The only one of the three candidates who did not support the chicken coup."

Ms Long-Bailey is standing against Keir Starmer and Lisa Nandy for the position.
