The role of Labour Party leader is up for grabs after Jeremy Corbyn announced he would step down following the party’s disastrous general election results in December. Now, the party must decide who tries to rebuild Labour support and form a strong opposition government.
All three remaining candidates will participate in Monday’s debate.
Shadow business secretary Rebecca Long-Bailey, Wigan MP Lisa Nandy and shadow Brexit secretary Sir Keir Starmer are all still in the running.
The 40-year-old shadow business secretary was the third candidate to make it on to the members’ ballot after securing backing from Unite, the Bakers, Food and Allied Workers Union, the Communication Workers Union and the Fire Brigades Union.
Seen as a Corbyn loyalist, she was one of a new generation of MPs on the left of the party.
She formed part of Mr Corbyn’s inner circle and represented Labour in an election TV debate last year.
She is widely regarded as the preferred candidate of Mr Corbyn and his shadow chancellor, John McDonnell.
But critics of the current leadership have accused her of representing “continuity Corbyn”.
In her candidate statement, Ms Long-Bailey said: “To realise collective aspiration, Labour must take on vested interests, not accommodate them.
“Whether we live Blyth or Brixton, my vision of aspirational socialism and a democratic revolution will excite a movement for renewal.”
The 40-year-old MP for Wigan became the second candidate to secure her place on the members’ ballot when she won the backing of affiliate group Chinese for Labour, on top of being backed by the GMB union and the National Union of Mineworkers.
On Friday, she also won the backing of the Jewish Labour Movement.
Ms Nandy worked in the charitable sector before entering politics in 2010, and became one of a group of shadow ministers who resigned from Jeremy Corbyn’s frontbench after the Brexit referendum.
She has become known for her support of smaller towns, saying the party needs to appeal to voters outside big cities if it is to win at the next election.
In her candidate statement, Ms Nandy said: “In December, voters sent us a clear message – change, or die.
