They then pushed the migrants back into the Jungle camp but had to contend with some inhabitants throwing rocks and responded by throwing smoke bombs.

The continuing unrest in Calais has prompted the mayor of the town to call for the Army to be deployed there to keep calm.

In a series of posts on Twitter Natacha Bouchart wrote: 'While police forces found themselves in serious trouble last night, I reiterate my call to the intervention of the army in #Calais.

'This is to ensure the safety of migrants and Calais. Delinquent migrants must be able to be identified and expelled.'

Meanwhile the migration crisis which engulfed Europe over the summer has led to a sharp rise in asylum-seekers in the UK.

The number seeking sanctuary in Britain in the three months to September hit 10,156 – up 64 per cent from 6,203 between April and June, said Home Office figures. It was the highest figure recorded for 12 years.

This increase coincided with the height of the chaos at Calais when some 5,000 immigrants camped in the city made desperate attempts to stowaway on lorries, trains and ferries to sneak over the English Channel.

Blaming the UK for the situation, French politicians said the migrants saw the country as a soft touch with lavish benefits and the prospect of illegal work and accommodation.
