Labour MP Jenny Chapman has said party leadership candidate Owen Smith should have been mindful of the "toxic atmosphere around politics … and used better words" in his pitch to head the party.
Among his campaign promises, Jeremy Corbyn's rival promised a tax on the rich and said he would ban zero-hours contracts.
But Smith has come under fire and was forced to apologise after saying he wanted to "smash" prime minister Theresa May "back on her heels" during a speech yesterday.
Chapman, the MP for Darlington and a supporter of Smith, explained that the MP for Pontypridd was trying to make a key point – but had chosen the wrong words to do it.
"I think he should have used better words," Chapman told Jonny Gould and Ash.
"There is such a toxic atmosphere around politics at the moment, and we're all trying to be extra mindful of how we express ourselves.
"I have heard other people say [something similar], but that doesn't mean it was an appropriate phrase to use in that context.
"He should have been more careful, but I think Owen recognises this.
"The point he's trying to make is that he will take the case to the Tories in a more forceful way than the Labour Party has done in the past few months."
