Outgoing British Prime Minister Theresa May will present Donald Trump with a copy of Winston Churchill's personal draft of the Atlantic Charter when they meet today.

The 1941 document set out the Allied goals for a post-war world, written by Churchill and Franklin D. Roosevelt.

It's the second Churchill-themed gift Trump has received on his state visit; yesterday, the Queen gave him a first edition of one of Churchill's books about the Second World War.

The monarch's speech at Monday's state banquet also nodded to post-war cooperation between the two nations, which is becoming something of a theme for the visit.
