Newspaper headlines: Theresa May's Brexit battle plan
Theresa May's Brexit plan "could see the UK quit the EU single market", according to many of Sunday's front pages.
"May's big gamble on a clean Brexit," is the main headline in the Sunday Telegraph, which reports the content of the prime minister's much-anticipated speech this week is being "closely guarded" by Number 10.
But citing "numerous government sources", the paper says the prime minister is expected to indicate she is prepared to take Britain out of the single market and the customs union.
"She's gone for the full works," a source tells the Sunday Telegraph. "People will know that when she said 'Brexit means Brexit', she really meant it."
The Sunday Times believes Mrs May will try to reassure voters who backed the Remain side, by suggesting that she could strike a transitional deal on Brexit, avoiding "a cliff-edge" for British business.
The Sunday People highlights what it says will be an appeal to everyone to unite behind Mrs May's vision for leaving the EU.
"The victors in the EU referendum have a responsibility to act magnanimously," the paper quotes pre-released extracts from the speech as saying. "The losers have a responsibility to respect the result."
The winter crisis in the NHS receives further coverage with the Observer reporting that "a large number of hospitals across the UK" have been cancelling some cancer operations since the start of this year.
The Mail on Sunday leads with the results of a Survation poll, which found that more than three-quarters of 12,000 people surveyed believed money from the foreign aid budget should be diverted to the NHS.
'Trump wants Putin summit'
The Sunday Times leads with a suggestion that Donald Trump is planning to hold a summit with Vladimir Putin, within weeks of becoming US President.
It says he hopes to emulate Ronald Reagan's Cold-War deal-making with Mikhail Gorbachev.
On its front page, the Observer carries a claim by the former Foreign Office minister, Chris Bryant, who says he's "certain" Russia is targeting senior British politicians, to try to find out potentially compromising details about their private lives.
On the letters page of the Sunday Telegraph, 50 Conservative MPs urge the government to bring in tougher strike laws. They want walkouts on "critical public infrastructure", such as train and bus services, to be banned unless a judge decides the action is proportionate.
The Sun on Sunday reports that the rail company Southern is preparing to recruit 200 part-time drivers to keep trains running during strikes.
First it was "trousergate", in which Theresa May's "high-end" wardrobe choices caused a storm, now she is to grace the pages of the world's most influential fashion bible. This is according to the Mail on Sunday, which reveals that the prime minister has posed for the renowned photographer, Annie Leibovitz, in a fashion shoot for American Vogue.
The Sun on Sunday says the aim is to make the Theresa May appear "more personable" to British voters.
But the Mail on Sunday takes a different view and says it is part of a Downing Street strategy to cosy up to the new administration in the White House, after being "wrong-footed" by the presidential election result.
"Theresa knows she needs to raise her profile in the US," a source tells the paper. "The Vogue shoot will form a central part of Operation Trump."
