Prime Minister Theresa May is currently in the United States for the United Nations General Assembly, and she gave her first address on Tuesday night.
We've put together a handy list of all the key points she has made both in her speech and during her trip to New York so far.
The migrant crisis
May used much of her address to the UN to set out the principles guiding her approach to the migrant crisis. She said that refugees should claim asylum in the first safe country they reach and nations have a right to protect their borders. She also called for a better distinction between genuine refugees and economic migrants.
A senior UK source said May's address, her first major speech on foreign policy, showed her view that "the more we do earlier on overseas, the better we can protect people at home".
At the summit, May also committed almost £750 million of aid funding to help tackle the migrant crisis. The Prime Minister said an extra £660 million of the aid budget would be diverted to focus on humanitarian relief - with much of the money expected to be used to support the refugees driven out by the bloody conflict in Syria. A further £80 million will be spent on creating jobs in Africa.
In her speech, May said that the UK will begin the process of ratifying the Paris Agreement within weeks.
She said: "We will continue to play our part in the international effort against climate change."
The agreement, which was secured at UN talks last December, enters into force when at least 55 countries accounting for 55% of the world's emissions have ratified it. Leading economies including the US and China have already ratified the agreement. So far, 29 countries totalling 40% of emissions have ratified the deal, with more expected to do so.
May insisted that Brexit will result in the "best possible" trade deal with the EU, in an effort to reassure nervous financial giants.
She met with major US firms while in New York amid concerns that they could shift their operations from the UK to elsewhere in Europe.
In an interview to be broadcast on Wednesday's Morning Edition on National Public Radio in the US, May said: "One of the purposes of my meeting with US investors, and that included US banks, was to hear from them what their concerns are and what their key issues are as we go forward for our negotiations.
"And I was able, I hope, to reassure them that I want to ensure the best possible deal for the UK in trade with the European Union, not just in goods but in services.
"I hope the message they took was that I recognise the importance of financial services and the City of London as an important international financial centre."
She also used her speech at the UN to stress that the UK remained a global player following Brexit. May said the UK remained a "confident, strong and dependable partner internationally".
While in New York, May also met Iranian president Hassan Rouhani and pressed him over a British-Iranian woman jailed for allegedly plotting to topple the Tehran government. Charity worker Nazanin Zaghari-Ratcliffe was apparently jailed for five years earlier this month - but the UK authorities have not been given details of the sentence or the charges.
May used her meeting to push for progress on the case, and is understood to have raised concerns about the charges and the sentencing.
May has insisted she will not allow an "industry of vexatious allegations" against British troops over claims of abuse in Iraq. Speaking to reporters travelling with her in New York, she said that allegations of criminal activity would be investigated properly but steps had been taken to tackle abuse of the system.
She said Britons should be proud of the work done by the armed forces and the disciplined way in which they operate.
May used a meeting in the margins of the General Assembly summit to push for international action to be taken on the criminal gangs behind the modern-day slave trade.
Ahead of the talks with leaders including Australia's Malcolm Turnbull and Nigerian president Muhammadu Buhari, May said she wanted the kind of international co-operation seen in the fight against drug trafficking and gun-running.
