Sir Keir was pictured grimacing when he left his house in Camden this morning.
for first time since humiliating loss.
The former lawyer has been hit with a devastating set of losses across the country at the polls.
In a historic loss, Labour lost its Commons seat in Hartlepool to the Tories in a by-election.
Labour has also lost scores of local council seats to the Conservatives with more humiliating results expected to come later today.
Tight-lipped as he met the awaiting journalists and photographers outside his house, Sir Keir Starmer is understood to have travelled to the Labour Party’s headquarters to assess the extent of the losses.
He is yet to make an official statement addressing the embarrassing defeat in Hartlepool.
The loss is particularly bruising because Labour’s candidate in the extraordinary vote was handpicked by Sir Kier.
Dr Paul Williams was the former MP for Stockton South between 2017 and 2019.
A staunch Remainer, Dr Williams was seeking to be elected in a seat that overwhelmingly voted to leave the EU in the 2016 referendum.
