The Deputy Mayor of Calais has struck out at David Cameron today, arguing the Prime Minister's response to the Calais migrant crisis is "racist" and "extremist".

Speaking to Channel 5 News on Friday, the official from the northern French town labelled Cameron's language towards migrants, desperate to make their way to England as racist and extremist, adding "I just can't accept them."

When asked if Cameron's use of the word "swarm" to describe the migrants attempting to seek refuge in the United Kingdom was extremist and racist, Philippe Mignonet replied "yes, or a proof of ignorance of the situation."

These comments come on the same day that the UK Government has pledged to come down harder on migrants hoping to cross from Calais to the United Kingdom, pledging more dogs, patrols and fences to keep people out.
