Newspaper headlines: Trump accuses May of 'wrecking Brexit'
The Sun says President Trump has ripped up the diplomatic playbook in their exclusive interview - criticising not only Theresa May's handling of Brexit, but also praising Boris Johnson as a "great" future prime minister.
The first seven pages of the paper are dedicated to its sit-down chat with Mr Trump which it describes as "incendiary", warning it will "pour nitro-glycerine" on the already raging Tory Brexiteer revolt against the prime minister.
Elsewhere in the interview, Mr Trump criticises the mayor of London, Sadiq Khan, as "terrible" and the president explains why he is spending so little time in London during his visit, saying "when they make you feel uncomfortable, why would I stay there?"
He also voices his fears that immigration into Europe will result in the continent losing its culture.
He tells the paper that allowing millions and millions of people to come very quickly is "very sad" - and that it's changed the fabric of Europe.
The New York Times describes President Trump's comments as "a remarkable breach of traditional protocol".
It says Mr Trump has put his brand of confrontational and disruptive diplomacy on full display "undercutting Prime Minister Theresa May hours after landing in her country".
It sums up his day as "a global disruption tour unlike anything undertaken by any other recent American leader".
The Washington Post says Mr Trump's comments cast an immediate pall over his visit - and stunned Downing Street.
According to Huffpost UK, Downing Street has pulled out all the stops in trying to design an itinerary to put Mr Trump in a good mood during his visit to the UK - a black-tie dinner at Winston Churchill's ancestral home in the gorgeous English countryside, tea with the Queen at Windsor Castle, and golf at his own course in Scotland.
But, it says, an indication of how the prime minister and Mr Trump lack a personal connection is that they are expected to spend just 10 minutes on their own when they meet at Chequers later, before a "working lunch" over Dover sole, Chiltern lamb and meringue pie.
The Daily Mail looks ahead to the meeting between the prime minister and the president at Chequers - when Mrs May's husband Philip will be assigned to look after Melania Trump.
It notes that the 60-year-old Oxford graduate and 48-year-old ex-model will make a very unlikely pairing.
Whereas at home he's the one who puts the bins out, the paper says Mrs Trump doesn't look as if she's in charge of recycling in the White House.
The Times says that Gareth Southgate has opposed the idea of a parade to celebrate England's achievement in reaching the World Cup semi-final, because he does not want the team to be regarded as heroes.
About 200,000 people in Luton welcomed home the last England team to reach the semi-finals of a World Cup in 1990, but the paper says there is little appetite among a tired squad for such an event.
