Theresa May is being urged to sack Foreign Secretary Boris Johnson – by some of his OWN supporters.

While MPs who backed him in the 2016 Tory leadership contest agree with what he says, they take exception to his lack of ­statesmanship in saying it.

In his latest outburst, Mr Johnson was recorded at a private dinner last week saying the PM’s Brexit strategy lacked guts, and Donald Trump would do a better job.

He also ­criticised Chancellor Philip Hammond’s Treasury as “the heart of Remain”.

Mr Johnson and Mrs May agree the UK must leave the EU customs union, which stops us doing trade deals with the rest of the world, and the single market, which allows unlimited EU migration.

But Mrs May is convinced a mutually beneficial deal can be struck with Europe. Mr Johnson is not so sure, and is more bullish about walking out of talks and into a no-deal hard Brexit.

partners.

Last month he angered MPs by asking for his own private plane so he wouldn’t have to take commercial flights on official trips. One Tory said: “He’s more demanding than my child. He’s obviously not used to hearing the word no.”

But if Mrs May does feel strong enough to wield the axe, she would then be faced with installing another Brexit big hitter at the Foreign Office.

That would make Environment Secretary Michael Gove’s promotion almost inevitable.
