The infamous settlement, near the entrance to the Channel Tunnel, is now home to an estimated 7,000 migrants, who are intent on trying to find a way to smuggle themselves into the UK.
Earlier this week, a coach full of British schoolchildren returning from a trip to Italy was attacked by a gang, who pelted the vehicle with bricks and smashed a window. It is believed the trauma of the attack caused one child to suffer an epileptic fit.
Mrs Seymour said: “These migrants are resorting to increasingly desperate measures in their efforts to reach Britain.
“Truckers who regularly run the gauntlet have been warning for months that it is only a matter of time before someone is seriously injured, or even killed.
“If these gangs are now prepared to pelt a bus full of terrified young people with bricks and smash windows, they clearly have no concerns over who gets terrified, or hurt.”
Mrs Seymour, one of UKIP’s three West Midlands MEPs, added: “It is an appalling situation, and one which the British and French governments seem content to ignore. The way they are apparently turning a blind eye is absolutely appalling – a disgrace.
“David Cameron insists that Britain will not be a safe haven for migrants from Calais, but it is clear that those who are trying to reach our shores every day simply don’t believe it.”
The infamous Jungle Camp at Calais has effectively become a permanent settlement after the French Government spent £20 million to rehouse more than 1,500 migrants in converted shipping containers.
Mrs Seymour said: “The conditions British people are facing, when simply trying to use the Channel Tunnel, are a scandal.”
