French president Francois Hollande has said he hopes authorities can relocate as many as 9,000 migrants massed in a squalid camp in Calais to reception centres across the country in the coming weeks.
Mr Hollande, visiting one of France's 164 such reception centres in the city of Tours today, reiterated his pledge to shut the Calais camp, known as "the jungle".
He said conditions there are "not acceptable", especially for those fleeing war.
The camp has become a symbol of his government's failure to tackle Europe's migrant crisis.
The reception centres will hold 40-50 people for up to four months, Mr Hollande said, as their cases are examined.
Migrants who do not seek asylum will be deported.
Many local conservative politicians have opposed the centres.
Mr Hollande is scheduled to visit Calais on Monday.
