THE Tories don’t trust themselves to tackle the climate emergency, Labour said today after Alok Sharma threatened to resign if the new prime minister fails to fully commit to delivering net zero by 2050. 

The Cabinet minister, who led last year’s Cop26 climate summit in Glasgow, raised concerns about the remaining leadership candidates’ “lukewarm” support for net zero in an interview with the Observer on Sunday. 

Urging candidates to “proactively” set out their support for the net zero agenda, he told the paper: “Anyone aspiring to lead our country needs to demonstrate that they take this issue incredibly seriously, that they’re willing to continue to lead and take up the mantle that Boris Johnson started off.”
