A charity has said the demolition of half of the notorious site could start as early as Thursday after the go-ahead was given by a French judge.

Save The Children told Sky News it hoped the clearance did not start immediately, arguing there was not enough alternative accommodation for those who would be displaced.

The area cannot be razed entirely because the court ruled common social areas such as schools, churches and mosques must be kept.

But Caroline Anning of Save The Children said: "What's the point of community infrastructure without a community?"

The official deadline for migrants to leave the southern, most populated part of the camp expired on Tuesday.

The authorities have said they will use force if necessary to move them to other accommodation in a nearby container park and reception centres.
