The leaders of the four largest Westminster parties are clashing in another TV set-piece.
The BBC is airing a two-hour episode of Question Time in Sheffield, where an audience will quiz Prime Minister Boris Johnson, Labour leader Jeremy Corbyn, Liberal Democrat leader Jo Swinson and Scottish First Minister Nicola Sturgeon for 30 minutes each.
Mr Corbyn struck a determined tone as he arrived at the venue.
Labour candidate for Hemsworth Jon Trickett posted footage of Jeremy Corbyn supporters gathered outside the Octagon in Sheffield ahead of the programme.
Prime Minister Boris Johnson said he was “excited” ahead of the event, while Lib Dem leader Jo Swinson was pulling no punches.
Meanwhile, Scottish First Minister Nicola Sturgeon did her homework on the way.
