Candidates for the Labour leadership are to make their pitch to activists after the surprise withdrawal of favourite Chuka Umunna from the race.
Declared contenders Andy Burnham, Yvette Cooper, Mary Creagh and Liz Kendall are all due to speak at the annual conference of the Progress think tank - as is fellow frontbencher Tristram Hunt, who is also expected to run. The party is still digesting the news from Mr Umunna that he is dropping his bid to succeed Ed Miliband in the top job.
Just days after formally declaring his candidacy, the shadow business secretary said he had "very real concerns" about the impact of his ambitions on "those close to me".
