Eurostar has suspended all services coming in and out of St Pancras International station after a protester made his way on to the roof wrapped in a St George's Cross.

A photo posted to Twitter appeared to show a man on top of the roof draped in a St George's Cross.

The intrusion also caused delays to Southeastern services, who said in a statement that services had to be brought to a stop as "the overhead wires can not be recharged".

Southeastern said on Twitter: "High Speed trains will not run to and from St Pancras due to the ongoing trespass incident just outside the station.

"The person is above the High Speed lines and as such the overhead wires can not be recharged."
