French president Francois Hollande has said he hopes Britain will vote to stay in the EU in the June 23 referendum.
Mr Hollande was speaking at a press conference with David Cameron at the conclusion of a one-day Anglo-French summit in the city of Amiens.
The summit was overshadowed by comments from French finance minister Emmanuel Macron, who suggested that migrant camps could be moved from Calais to the UK if Britain votes to leave the EU.
Mr Hollande did not repeat his warning, but left no doubt that he wants a Remain vote in the referendum.
"I hope the UK remains in Europe," said the French president. "It is in the interest of the UK, it is in the interest of Europe, but the people are always sovereign."
