On 28 June 2016, he lost the vote of confidence by Labour Party MPs by 172–40.
He said with a statement that the motion had no "constitutional legitimacy" and that he intended to continue as the elected leader.

A YouGov poll of Labour party members found that about 50% expected to support Corbyn if a leadership ballot was called.
London Mayor Sadiq Khan, who did not take a side in the dispute, said "When Labour splits, when we're divided, we lose elections".
The division between Corbyn and the Labour parliamentary party continued.

On 11 July 2016, Angela Eagle announced her candidacy to run against Corbyn in the upcoming 2016 Labour Party leadership election.
On 13 July former shadow minister Owen Smith also announced his leadership challenge.
On the 19 July, Eagle quit the race after Smith got 90 nominations to her 70.
Eagle said she resigned 'in the best interests of the party.'
This was because having two anti Corbyn candidates in the race could split the vote and give him a better chance of winning.

On 24 September 2016, following the leadership contest, Corbyn was re-elected as the leader of the party again with an increased majority of 61.8%.
