The French government’s plan to clear part of the Calais migrant camp known as the “Jungle” has been approved by a court in Lille.
Authorities say around 1,000 migrants will be affected by the eviction plan for the southern part of the camp.
Aid agencies say the number of people living there is much higher.
Local officials said public areas such as places of worship or schools would not be cleared and said it would be a “humanitarian operation”.
A deadline had initially been ordered for the southern part of the “Jungle” to be cleared by Tuesday evening but activists appealed to the court to halt the evictions.
The judge visited the camp as she considered her ruling.
Conditions there are squalid and its sprawling presence has become a controversial issue in both France and the UK.
