Britain's foreign minister Boris Johnson has been accused by cabinet colleagues of "backseat driving" on Brexit after setting out his own vision of the country's future outside the European Union.
- Boris Johnson wrote an article on Brexit that went beyond his ministerial brief
- The move reignited speculation he will challenge Theresa May's leadership
- Cabinet members insist Ms May is 'driving the car' on Brexit talks
Only days before Prime Minister Theresa May was due to speak in Italy about Britain's planned EU departure, Mr Johnson published a 4,300-word newspaper article that roamed well beyond his ministerial brief, and in some cases the approach set out by the Government.
Mr Johnson's article re-ignited speculation that he will challenge Ms May for the leadership of the Conservative Party.
Interior Minister Amber Rudd said it was "absolutely fine" for the Foreign Secretary to intervene publicly but that she did not want him managing the Brexit process.
"What we've got is Theresa May managing that process, she's driving the car," Ms Rudd told the BBC.
Asked if Mr Johnson was backseat driving, she replied: "Yes, you could call it backseat driving, absolutely."
However Ms Rudd said she did not think Mr Johnson was laying the groundwork to challenge Ms May.
"I think that he, like I, supports the Prime Minister at this difficult time as we try to conclude the negotiations with the EU," she said.
Reacting to the furore his article had generated, Mr Johnson tweeted that he was "looking forward" to Ms May's speech.
Ms May's deputy, Damian Green, also weighed in, saying that Mr Johnson had written a "very exuberant" article but it was "absolutely clear to everyone that the driver of the car in this instance is the Prime Minister".
"It is the job of the rest of us in the cabinet to agree on a set of proposals and get behind those proposals and get behind the Prime Minister.
'Misuse of statistics'
Mr Johnson wrote in the Daily Telegraph newspaper on Saturday (local time) that Britain would not pay to access the EU market in the future.
Once out of the EU, the country should borrow to invest in infrastructure, reform the tax code and set immigration levels as it sees fit, he said.
Mr Johnson also repeated the Brexit campaign claim that the Government would be 350 million pounds ($594 million) a week better off outside the EU.
Government officials criticised Mr Johnson for repeating the claim, saying the figure does not take into account the funding Britain receives back from Brussels.
David Norgrove, of the UK Statistics Authority, said he was "surprised and disappointed" that Mr Johnson was still quoting a figure that confused gross and net contributions.
"It is a clear misuse of official statistics," Mr Norgrove said in a letter to Mr Johnson.
The foreign minister said in reply that Mr Norgrove's letter was "based on what appeared to be a wilful distortion of the text of my article" and asked the official to withdraw it.
The timing of Mr Johnson's article — published a day after a bomb injured 30 people on a train in London — also drew criticism from some colleagues.
