Theresa May has spoken to congressmen from the Republican Party ahead of her meeting today with Donald Trump.
The British Prime Minister said the two countries had a “responsibility” to offer leadership to the rest of the world.
Her speech appeared to evoke the memory of Margaret Thatcher and Ronald Reagan as she called on the US to renew its special relationship with the UK.
Here’s everything you need to know:
1. May laid out her thoughts on some of the US president’s key foreign policy priorities.
She signalled support for some of Trump’s foreign policy priorities, condemning the “malign influence” of Iran, vowing to fight the Daesh terror group and promising to “stand up” for the security of Israel.
But Mrs May also sounded notes of caution over foreign policy positions taken by Trump on the campaign trail, warning that his watchword with Vladimir Putin’s Russia should be “engage but beware”.
She described the Iran nuclear deal – which Trump has threatened to tear up – as “vitally important for regional security”.
And she spoke out in support of the importance of international institutions like the UN, IMF and Nato, often the target of Trump’s scorn, in maintaining global peace and prosperity.
2. She evoked the close Reagan-Thatcher relationship.
Mrs May’s pointed references to the close Reagan-Thatcher relationship will fuel suspicions that she is hoping for a similar partnership with Trump, who has reportedly started referring to her as “my Maggie”.
Asked by reporters whether she would struggle to strike a rapport with the brash property tycoon and reality TV star, Mrs May said: “Haven’t you heard? Sometimes opposites attract.”
Mrs May also made no attempt to dissuade her audience from drawing parallels with the US and UK leaders of the Cold War era.
She warned: “We should not jeopardise the freedoms that President Reagan and Mrs Thatcher brought to Eastern Europe by accepting President Putin’s claim that it is now in his sphere of influence.”
3. She praised Trump for his election victory…
In a clear attempt to mend fences with a man whose campaign policies she once described as “divisive, stupid and wrong”, Mrs May went out of her way to praise Trump’s election victory and stress common threads between the Conservatives and Republicans.
Both parties believe in “the value of liberty, the dignity of work, the principles of nationhood, family, economic prudence, patriotism – and putting power in the hands of the people”, she said.
And she said Trump’s victory would allow the US to be “stronger, greater, and more confident in the years ahead”, just as the Brexit vote would restore Britain’s sovereignty and independence.
4. … but added there would be occasions where the leaders disagreed.
Speaking shortly after voicing differences with Trump on the use of torture, Mrs May said: “There may be occasions on which we disagree. But the common values and interests that bring us together are hugely powerful.”
She dismissed those who predict “the eclipse of the West” in the face of emerging giants like China and India and the threats of economic instability and Islamist terrorism.
The US and UK had a “joint responsibility to lead, because when others step up as we step back, it is bad for America, for Britain and the world”, said Mrs May.
“The world is passing through a period of change – and in response to that change we can either be passive bystanders, or we can take the opportunity once more to lead. And to lead together.”
5. She insisted that the days of Britain and America interfering in the affairs of sovereign countries are over.
Mrs May warned against military adventures of the kind undertaken in Iraq and Afghanistan by Tony Blair and George Bush, insisting that the days of Britain and America “intervening in sovereign countries in an attempt to remake the world in our own image are over”.
But she added: “Nor can we afford to stand idly by when the threat is real and when it is in our own interests to intervene.
“We must be strong, smart and hard-headed. And we must demonstrate the resolve necessary to stand up for our interests.”
6. May is the first foreign head of government to address the annual Republican Congressmen’s Retreat.
In a sign of her determination to deepen links with the Republican establishment as well as the team around Trump, she held private talks with House of Representatives Speaker Paul Ryan and Senate majority leader Mitch McConnell, as well as the Foreign Affairs Committee chairmen of the two houses of Congress, Ed Royce and Bob Corker.
