Theresa May has told Republicans in Philadelphia that relations between the UK and the US have "defined the world," delivering a speech greeted by frequent loud applause.

“I speak to you not just as Prime Minister of the United Kingdom, but as a fellow Conservative who believes in the same principles that underpin the agenda of your Party," the Prime Minister said on Thursday.

“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.

“I know that it is these principles that you have put at the heart of your plan for government."
