David Cameron has accused the current prime minister, Boris Johnson, and Michael Gove of behaving “appallingly” during the EU referendum campaign.

Speaking to the Times ahead of his book launch, the former Tory PM attacked some Leave-backing colleagues for “trashing the government”.

Cameron said the result in 2016 had left him “hugely depressed” and he knew “some people will never forgive me”.

He also said another referendum cannot be ruled out “because we’re stuck”.

The former PM criticized Johnson’s strategy for dealing with Brexit, including his decision to suspend Parliament ahead of the 31 October deadline and removing the whip from Tory MPs who voted to block a no-deal Brexit.

But Johnson said the suspension – or prorogation – was a normal action of any new government to let them lay out their new policies in a Queen’s Speech, and blocking no-deal would “scupper” his negotiations with the EU.
