"It was a legitimate criticism," she said of Farage's outburst against the audience. "The crowd didn't seem very balanced at all – it was so left-wing."

"As is always the case, those who shout the loudest get heard. but there was a quiet group of us in there listening carefully to the arguments. The debate was actually a bit of a farce – there were four left-wing leaders and Nigel Farage.

"I don't usually like UKIP at all but he was the only one who stood out, and he made a completely fair point about the audience."

Of the four non-UKIP leaders, she said Nicola Sturgeon was "good on her feet" but added that she completely disagrees with the SNP aim to break up the UK.
