An election debate organised by The Star and the BBC has been postponed as a result of the terror attack in Manchester.
Young people and first time voters were due to question candidates at an event called 'Purdah on the Dancefloor' at The Leadmill tomorrow.
But politicians have suspended their General Election campaigns as a result of the suicide bombing at Manchester Arena, in which 22 people died, and tomorrow's debate has also been put on hold.
A new date for the event has not yet been set.
People can still apply to take part. The candidates confirmed so far are:
Louise Haigh - Labour, Sheffield Heeley
Shaffaq Mohamnmed - Liberal Democrat, Sheffield Hallam
John Booker - UKIP, Penistone and Stocksbridge
Natalie Bennett - Green, Sheffield Central
The debate will be chaired by BBC Look North presenter Harry Gration.
