Jeremy Corbyn has vowed to fight a leadership challenge from former shadow business secretary Angela Eagle as peace talks aimed at resolving the crisis at the top of the UK Labour Party collapsed.
The Labour leader's spokesman said it was "disappointing" that his deputy Tom Watson had walked away from the union-brokered talks which were attempting to end the impasse between the embattled Mr Corbyn and his MPs.
The collapse of the talks prompted Ms Eagle to announce her intention to fight for the leadership, saying Mr Corbyn had failed "to lead an organised and effective" Parliamentary Labour Party and she would set out her "vision for the country" on Monday.
A spokesman for the party leader said: "Jeremy Corbyn has reached out to Labour MPs and made clear he wants to work with them to carry out his role as elected leader of the party.
"Jeremy regards the talks with trade union leaders as a vehicle to bring people together, and it is disappointing that some have walked away from them.
"Jeremy is committed to fulfilling all his responsibilities as democratically elected leader and will not betray the hundreds of thousands of people who elected him for a different direction for the Labour Party and a different kind of politics.
"He continues to be fully committed to working with the Parliamentary Labour Party and is ready to talk with as many people as necessary to assist that process, discussing policy initiatives and listening to ideas.
"He will remain leader of the Labour Party and will contest any leadership challenge if one is mounted."
