As it happened: Coverage and reaction to the Question Time performances - BBC News
Jeremy Corbyn, Nicola Sturgeon, Jo Swinson and Boris Johnson faced tough questions from the audience.
It's not clear if the lively grilling of major politicians will shift the dial at this election.

But it certainly marked a shift in Jeremy Corbyn's position on Brexit.

He had been put under pressure by his opponents to say whether he would support Leave or Remain in the new referendum Labour is promising.

So he tried to eliminate a negative by providing clarity, of a sort: a clear commitment to stay neutral.

Labour's strategists are suggesting he could now be seen as an honest broker that can bring a divided country together.

In truth, though, behind the scenes there are fears that the party may have over-estimated the threat from the Lib Dems and underestimated the importance voters in Leave areas attach to delivering Brexit.

So his neutrality is in part an attempt to reassure those voters that his promised referendum isn't the means of cancelling Brexit by the back door.

His followers will say he has risen above the fray; his critics - that he has become more decisive about sitting on the fence.
