Labour leadership front runner Jeremy Corbyn is to speak at a rally in Sheffield next weekend - just days before a winner is confirmed.
The candidate in the party race to replace former leader Ed Miliband, who stood down in the wake of the general election result, will address crowds at The Crucible theatre on Saturday August 29 from 2pm.
Organisers also say that Tudor Square will be available for an overflow in case the 900-seat theatre is full.
The winner of the leadership contest is to be announced on September 12, with Andy Burnham, Yvette Cooper and Liz Kendall also vying for the title.
Max Munday, who is co-ordinating the Sheffield event, said Mr Corbyn’s campaign had brought thousands back into politics or introduced them to it.
He said: “The Crucible is a perfect venue to show the strength of feeling of this movement. The atmosphere will be electric.
“Whilst there has been understandable media scrutiny, as well as wild accusations, this is an opportunity for people to hear first hand, the policies of Jeremy Corbyn and to quiz him on the things that matter to them.”
The rally will begin at 2pm and people are asked to register at www.jeremyforlabour.com/events.
