Audience members in tonight's ITV election debate burst out laughing tonight as Boris Johnson said the truth matters.

The Tory leader was briefly shamed - and even hit by an inaudible heckle - as he made the bold claim in the studio in Salford.

Asked by host Julie Etchingham "does truth matter", he replied: "I think it does".

A ripple of laughter went through the audience - and someone shouted out at the PM, who was twice sacked from previous jobs for lying.

It wasn't all plain sailing for Jeremy Corbyn either though.

Labour's leader also suffered laughter as he said his Brexit position was "clear", despite Labour not yet knowing how it'll campaign in a second referendum six months after taking office.

And others laughed when Mr Corbyn said a four-day week would be "paid for by productivity increases" across the economy.

Mr Johnson made the claim despite telling at least four lies or half-truths in the debate - mostly about Labour.

The Tory leader said the only reason Britain was having an election was because "Parliament won't deliver Brexit" - even though he triggered it because MPs simply asked for more time for debate.

He said Mr Corbyn would raise corporation tax to the highest level in Europe, despite there being higher rates than Labour's planned 26% in France (32%), Portugal (32%), Germany (30%), Belgium (30%), Greece (28%) and Italy (28%).

And he repeated his claim that he is building 40 "new hospitals", despite the fact the pledge is over a long period and includes renovations of existing hospitals.

It came as the pair clashed on ITV in the first live TV debate of the general election .

The leaders of the UK's two major parties went head-to-head in an hour-long debate hosted by Julie Etchingham in Salford's MediaCityUK.

The Lib Dems and the SNP yesterday lost a High Court battle to have their leaders included in the debate.

A snap YouGov poll found Boris Johnson won the debate - only just.

Some 51% of those polled said Mr Johnson won while 49% went for Jeremy Corbyn.
