US President Barack Obama has said that the Northern Ireland Peace Process has become an inspiration to the rest of the world and that he is pleased to see "tribal mentalities" broken down.
President Obama was speaking at an event in London as part of his official visit to the UK.
Today he answered questions from young British people at a town hall event and visited the Globe theatre to celebrate the 400th anniversary of Shakespeare's death.
Later in the day the US president played a round of golf with British Prime Minister David Cameron at an exclusive course north of London, making time in a busy overseas travel schedule for his favourite weekend pastime.
The game at The Grove, a resort that is due to host the British Masters tournament later this year, is a sign of the close personal relationship between the two leaders; President Obama rarely mixes business with his preferred way to take a break, and almost always plays golf with friends and staff.
President Obama and Mr Cameron were to dine together this evening at the US ambassador's residence in London, the last scheduled event of a three-day trip which President Obama has spent urging Britons to vote to stay in the European Union.
Tomorrow, President Obama heads to Hanover, Germany for talks with Chancellor Angela Merkel, and a leaders' meeting on Monday that will also include Mr Cameron, French President Francois Hollande, and Italy's Prime Minister Matteo Renzi.
