The three remaining Labour leadership candidates will go head-to-head on a Channel 4 debate this evening.
Keir Starmer, Rebecca Long-Bailey and Lisa Nandy have all made it through to the final stage of the party's race to replace Jeremy Corbyn as leader after Emily Thornberry failed to drum up enough backing to make it through to the final members' ballot.
Sir Keir is the early favourite and has picked up endorsements from key trade unions such as Unison, along with more than half of all constituency parties.
Ms Nandy on the other hand has received the support of the GM and the Jewish Labour Movement, while Ms Long-Bailey, the shadow business secretary, has won the support of Unite.
The four contestants are set to showdown on a special Channel 4 show this evening. Here's all you need to know about it.
What time is the Labour leadership debate?
The show will be broadcast at 8pm on Monday, February 17.
Channel 4 will air the show this evening, following on from the debate they hosted back in January.
