US President Barack Obama has said Britain would go to the "back of the queue" for trade deals with the US if it votes to leave the European Union.
He said Britain was at its best when "helping to lead" a strong EU and membership made it a "bigger player" on the world stage.
He was speaking at the start of a three day visit to the UK.
