US President Donald Trump has arrived at Stansted Airport ahead of a four-day trip.
Air Force One, the President's official jet, landed just before 2pm this afternoon (12 July).
Donald Trump will be accompanied by as many as 1,000 staff, a motorcade and multiple helicopters during his UK trip.
Police and security services have been patrolling the area ahead of his visit.
The visit has sparked some protests in the region - including one in Cambridge.
During Mr Trump's trip he and his wife Melania will meet the Queen and Prime Minister Theresa May, as he visits locations including Blenheim Palace, Windsor Castle, the US ambassador's official residence in Regent's Park, London.
The visit has prompted one of the UK's biggest ever police operations, with thousands of officers on duty.
Essex Police Federation says the visit is stretching resources to the limit.
