Two ministers touted as a potential caretaker PM in reports of a cabinet coup say they fully back Theresa May. Environment Secretary Michael Gove told reporters it was "not the time to change the captain of the ship". And the PM's de facto deputy David Lidington insisted he was "100% behind" Mrs May. Meanwhile, the Brexit secretary said an election will become more likely if MPs vote this week for a Brexit option the government does not want. MPs are expected to get the chance to hold a series of so-called indicative votes on possible alternatives to Mrs May's withdrawal deal, but Brexit Secretary Stephen Barclay said they would "not be binding". He was among the Tory MPs and ministers at talks with Mrs May on Sunday at Chequers, her country retreat. Prominent Brexiteers Mr Gove, Boris Johnson and Jacob Rees-Mogg were also present. They discussed a range of issues, including whether there was sufficient support to hold a third vote on the prime minister's deal this week, a Downing Street spokesman said. 'Serious manoeuvring'Newspapers claim cabinet ministers are plotting a coup against the prime minister, aiming to replace her with a caretaker leader until a proper leadership contest is held later in the year. The suggestion is that Tory MPs might reluctantly back Mrs May's Brexit deal if they know she will not be in charge of the next stage of negotiations with the EU, but there are differing accounts of who the preferred candidate to replace her is. The Sunday Times reports that Mr Lidington, who voted Remain, is being lined up, while the Mail on Sunday said the Brexiteer Environment Secretary Mr Gove was the "consensus choice". AFP.
