Reports that a death in the Channel Tunnel has caused today's delays. More later.
Another migrant has been found dead after apparently making a bid to cross to Britain through the Channel Tunnel in France.
The man, an Eritrean aged in his 20s, is believed to have been hit by a freight train near the entrance at around 1am.
Channel Tunnel operator Eurotunnel said the person was found unconscious near the tracks outside the tunnel.
A spokesman said: "It's another very regrettable incident which serves to highlight the risks associated with crossing the Channel illegally."
Eurotunnel said it "deplored" the accident, which had no impact on the flow of services. The shuttle driver and colleagues will receive psychological care.
The man is the 13th migrant to die since the start of the cross-Channel migrant crisis, which has placed UK police and social services under huge strain.
