Labour's deputy leader has indicated that Andy Burnham would have triumphed in the Gorton and Denton byelection, as she urged her party to leverage the popular Greater Manchester mayor.
Overcoming a substantial 13,000-vote Labour majority from the last general election, Hannah Spencer, a community tradesperson, became the Green Party's fifth MP on Friday. This occurred in an area that had consistently returned Labour MPs for nearly a century.
The Reform Party's Matt Goodwin placed second, just ahead of the Labour candidate, Angeliki Stogia.
The unexpected outcome has prompted renewed questioning of the party's choice to block Andy Burnham from contesting the seat last month.
In an interview with the BBC, Labour's deputy leader, Lucy Powell, remarked, "Andy Burnham probably would have held the seat. I think definitely the Greens wouldn't have gone after the seat in the same way that they did."
Powell was the sole member of Labour's ruling national executive committee to support allowing Burnham to stand, with eight others, including leader Keir Starmer, opposing the move.
However, she stated she understood "the group's decision" for the outcome, pointing to worries over triggering a mayoral byelection in Greater Manchester.
Powell also emphasized that her party must learn from the sources of Burnham's widespread popularity in the region. She said people "view him as someone who is on their side, someone who is implementing those core principles and Labour policies."
"It is essential we draw on that, leverage Andy Burnham, but also draw on that and reflect on how we could replicate that success nationally," she continued.
Andy Burnham is reportedly considering another attempt at returning to parliament. One ally said, "Given the current political climate, who knows what might happen. It would be foolish to say he would never."
So far, Burnham himself has yet to comment on the byelection result. Meanwhile, Keir Starmer has pledged to continue despite labelling the poll result "disappointing."
Angela Rayner, a prominent voice on Labour's left, described the byelection result "a stark warning" for the party.
Meanwhile, the Home Secretary is set to warn against the party shifting leftward in response to the defeat. This comes as she introduces new laws on tougher immigration measures next week.
A source close to the Home Secretary was quoted as saying, "The Labour government should not misinterpret the message from its recent byelection loss. The idea that we are alienating support over immigration is simply incorrect."
