Operation Stack causes delays on road to Channel Tunnel

Drivers attempting to cross into mainland Europe through the Channel Tunnel have been warned to expect more delays as Operation Stack is in effect.

The operation means that the M20 in Kent is blocked by parked lorries that are unable to cross.

Eurotunnel said hundreds of people, hoping to cross illegally into the UK, have tried to break into the terminal in Calais overnight, leading to the delays.
