David Miliband, Ed Miliband and Ed Balls will all be present, while Andy Burnham and Diane Abbott are planning to campaign outside London on the night.
This is your opportunity to ask the candidates your questions and speak to them in the reception afterwards. It promises to be an extremely interesting meeting, coming as it does, just as the leadership contest approaches its climax.
Please note that timings for this event have changed slightly.
Registration and a pre-event drinks reception will take place from 7pm with speeches and questions for the candidates from 7.30 – 8.30pm.
Places are limited so if you would like to attend this event, please register online here.
