The deputy prime minister has warned that Sir Keir Starmer will fight to stay on as prime minister and urged the Labour Party to 'stop the own goals' after a week of infighting. David Lammy said the ruling party would lose the next general election if the “internecine warfare” of the last 10 days continued. But he said he would campaign for Andy Burnham in the Makerfield by-election, which the Greater Manchester Mayor will need to win to mount a challenge for No 10. #LabourParty #KeirStarmer #AndyBurnham #DavidLammy #C4News
