Theresa May meets Donald Trump in Washington: As it happened

The press conference has ended and the pair have gone for lunch. Here is a summary of the key takeaways:

• Theresa May said that Donald Trump is "100% committed" to Nato.
• She said that there "is much we can agree on".
• Trump said "The special relationship between our two countries has been one of the great forces in history for justice and for peace."
• Trump has accepted an invitation by the Queen for a state visit to the UK later this year.
• May said the pair will discuss how to progress immediate high-level talks on trade and that a deal is in the national interests of both countries.
• Ahead of Trump's phone call with the Russian president, Vladimir Putin on Saturday, May said she wants sanctions against Moscow to continue until the Minsk agreement is implemented.
• Trump has backed Brexit which he has described as "a fantastic thing".
• On Mexico, Trump said the US cannot continue to "lose vast amounts of business, vast amounts of companies and millions and millions of people losing their jobs".
• Trump said he would defer to his defence secretary on the issue of torture. Of James Mattis, he said he "does not necessarily believe in torture or waterboarding - I don't necessarily agree, but he will over-ride. He's highly respected so I'm going to rely on him."

Trump was asked about his relationship with the Mexican president and criticism that he has already soured the relationship with his pledge to build a wall on the border.

He said that the US cannot continue to lose jobs and will renegotiate trade deals, which will be good for both countries.

He added that his call with the Mexican president was "very friendly" and that they will negotiate over the coming months.

Trump said regarding torture, he will defer to the defence secretary, James Mattis, but "I happen to feel it does work".

The leaders are taking questions from journalists and Trump is asked about concerns expressed in the UK about punishment for abortion, banning of Muslims and ties with Russia.

"There goes that special relationship", Trump replies.

On sanctions against Russia, May has said: "We believe the sanctions should continue until we see the Minsk agreement fully implemented."

Theresa May has spoken optimistically about the prospect of a good trade deal with the US.

"I'm convinced that a trade deal between the US and UK is in both our national interests," she said.

Trump gives his backing for Brexit.

He says:

"We pledge our lasting support to this most special relationship together America and the United Kingdom are a beacon for prosperity and the rule of law. That is why the United States respects the sovereignty of the British people and their right of self-determination."

Donald Trump has said he is "honoured" to have prime minister Theresa May for the first official visit from a foreign leader.

"The special relationship between our two countries has been one of the great forces in history for justice and for peace and by the way, my mother was born in Scotland, Stornaway, serious Scotland."

The leaders have taken to the stand, Theresa May is speaking second and she has said: "There is much we can agree on".

More from the body language expert, Judi James, about the rapport between May and Trump.

She tells IBTimes UK:

"The spot where the host goes to greet the visitor tells everything about status. In what's called an act of inconvenience the further you walk to greet the higher you consider your guest.

"May's car came almost right to the door and Trump then emerged from that door, performing a much more intimate moment of face-to-face welcome and eye contact than is usual at The White House.

"He greeted her very much as an equal and then extended his hand to her arm, less in a pat of power to put her in her place but more in a mimed embrace, suggesting genuine warmth.

"They posed for the cameras with May retaining a dignified smile that gave very little away and it was telling that it was May who nodded her head briskly to signal and end to the photo-call.

"Hopefully taking control at that stage hints she intends to take some form of control during the meeting that follows."

The body language expert Judi James has looked at the first meeting between the prime minister and the president and has come up with her analysis of how they acted around each other.

She tells IBTimes UK:

"Political greeting rituals famously define perceptions of power, status and intent in the relationships so the very first moments between Trump and May told much about how they viewed the meeting that was to follow.

"To date, Trump has been treating his meetings with UK political names either like selfie moments with a fan, (Trump and Farage's grinning thumbs-up outside the Trump Towers Golden Doors) or lowly interviewee chats (Gove's lower chair making him look like a school kid in the head's office during his meeting at Trump Towers) but for May, he pulled out some far more diplomatic and respectful body language."

It has been a turbulent first week for Donald Trump, with controversies already stemming from his views on waterboarding, building a wall alongside the Mexican border and how he has described the media.

The meeting with Theresa May could see things get a bit better though as we take a look back at Trump's first seven days in office.

A good relationship has been helped by poetry and many have been taking to Twitter with their odes to Theresa May and Donald Trump.

#PoemsAboutTrump has been trending on Twitter and here are some of the best rhymes.

Theresa May told an audience in Philadelphia on 26 January that the UK and the US have a "unique and special relationship" that has defined the modern world.

The term special relationship, describing ties between the US and the UK, was first coined by Winston Churchill and has been a motif that has echoed down the decades.

IBTimes UK looks at the origins of the relationship.

Before he took the oath last week, Donald Trump had some of the lowest approval ratings for an incoming president. Seven days in, that appears to have changed, although it is spread out over a wide margin.

IBTimes UK drills down into some of the figures.

Speaker of the House, Paul Ryan, has said he had an "excellent discussion" with Theresa May about the special relationship.

The so-called "special relationship" has got off to a start as the pair met on the steps of the White House.

The leaders are engaged in face-to-face talks in the Oval Office, with Britain looking for a free trade deal following its vote to leave the European Union.

Trump's press secretary Sean Spicer has tweeted an image of May signing the visitors' book.
