Channel Tunnel: UK offers £7m to boost Calais security
Eurotunnel has revealed that around 2,000 migrants attempted to storm the French terminal at Calais on Monday night.
Police confirmed it was the biggest attempt to make the dangerous journey to Britain in recent weeks.

She promised up to £7m to boost security at Calais.
