Veteran left-wing MP Jeremy Corbyn received the warmest welcome of all the candidates at a Labour leadership campaign hustings.
All three of his rivals were booed and heckled on the issue of renewing Trident, and for refusing to condemn Tory welfare reforms.
Jeremy Corbyn was nominated for the Labour leadership to ensure that the party's members had the widest possible choice of candidates to consider, some MPs have said.
However, Labour backbencher John Mann was scathing about Mr Corbyn's presence on the ballot paper.
"So to demonstrate our desire never to win again, Islington'sJeremy Corbyn is now a Labour leadership candidate," Mr Mann said on Twitter.
The Democratic presidential candidate may also have shown his cards on his choice of running mate.
The US president also shared a post on Twitter accusing Dr Anthony Fauci of misleading the public over hydroxychloroquine.
