Boris Johnson has waded into the row over Rishi Sunak’s plans to U-turn on some of the government’s net zero commitments, warning his successor that he “cannot afford to falter now” or “lose our ambition” for the country.

The former prime minister, who oversaw the introduction of many of the targets during his tenure, said “businesses must have certainty” about the UK’s net zero commitments, as companies reacted with alarm to the potential policy shift.
