Andy Burnham faces a test of his re-energised Labour Party on Thursday as voters turn out to decide who will replace Sir Keir Starmer as MP for St Holborn and St Pancras.
Local council leader Sagal Abdi-Wali is hoping to hold the seat for Labour after the former prime minister announced he was resigning as an MP last month.
But she will still have to fend off a challenge from the Green Party, who will be fielding party leader Zack Polanski as their candidate.
It has been a difficult week for Mr Polanski, however, after the Greens passed a controversial motion at their conference in Brighton asserting that “Zionism is racism”.
The election will offer Mr Burnham a chance to show he is restoring voters’ faith in the Labour Party, after its poll ratings nosedived during Sir Keir’s time in No 10.
There are 13 other candidates in the by-election, including Tory candidate Ewan Cameron, Reform UK’s Peter Newman and the Liberal Democrats’ Patrick Thomas Stillman.

Polanski says election is 'looking close today'
11:30 , Maryam Zakir-HussainAhead of polls opening on Thursday, the Green Party leader said: “The election is looking close today.

“On the climate crisis, today is the day to say clearly to Labour, ‘no new drilling in the North Sea’ – a decision they chose to delay until after the by-election result. That makes your vote powerful.
“A vote for the Greens today can show Labour the right direction. Make it happen today.”

Prime minister has 'no doubt' Labour's candidate will make 'brilliant local MP'
09:45 , Maryam Zakir-HussainAndy Burnham said he has “no doubt” Labour’s candidate in the by-election, Sagal Abdi-Wali, will make a “brilliant local MP”.
He said: “Today, hope can win. But only if you vote for it.
“This area gave Sagal a home when she arrived here as a refugee in the 1990s. Camden gave Sagal and her family hope. Now she wants to give that back to the communities that have always been there for her.
“It’s hard to think of someone more committed to their local area and the care of people than Sagal.
“Sagal has a plan to take on vested interests in our water industry, to work with me to help end rough sleeping, and to make sure every young person has the opportunities they deserve to get on in life.
“Sagal is bursting with energy and positivity. She’s given so much to Camden already, and I know she has so much more to give. For Camden, for hope, vote for Labour’s Sagal Abdi-Wali today.”
