British families start cancelling holidays to France as crisis in Calais grows after striking ferry workers block roads with burning tyres

Striking French ferry workers set fire to the roads (pictured) leading to the port of Calais, blocking the port off with a wall of burning tyres in the latest wave of disruption faced by British tourists. People heading for France for their summer holidays already face travel chaos as they contend with the migrant crisis (inset) in Calais and Operation Stack in Kent. The crisis has forced some British families to cancel their holidays, while others are changing their travel plans to avoid the French port. Meanwhile thousands of British tourists could be diverted onto ferries instead of using the Channel Tunnel.
