Boris Johnson flipped out on live TV following the party leader's Question Time yesterday
Mr Johnson said the Labour Party had been taken over by a "crypto-communist cabal" headed by Jeremy Corbyn, Diane Abbott and John McDonnell.
He added that Mr Corbyn's performance on the debate stage tonight showed his "contempt" for businesses and people getting by.
The Tory cabinet minister then hit out at the Labour leader's stance on the nuclear weapons.
He told the BBC: "The most chilling thing of all is that we cannot guarantee that we will be immune from nuclear blackmail.
"And here was Corbyn saying to the world that he would be vulnerable to that blackmail because he would never press the button itself."
However, Mr Lavery hit back at this and said that said that Boris Johnson was not fit to lead the UK into Brexit talks.
He lashed out at Mr Johnson's elitism and said: "I don’t think you understand ordinary people Boris. You have never been in an ordinary constituency.
"You have never even been to a food bank."
