'We won't let migrants return to Calais'

The French Ambassador to the UK has said that French authorities will ensure migrants no longer come to Calais.

More than 2,300 migrants voluntarily left the "Jungle" migrant camp in Calais on Monday, taken on buses to reception areas across France.

Sylvie Bermann told the Today programme that all unaccompanied children could leave France if Britain will let them in.
