A man has been charged over a stunt on the Eurostar which caused travel disruption for thousands of passengers between London and Paris at the weekend.
Terry Maher, 44, from Camden in north London, will appear before magistrates on Monday after being charged with obstructing the railway and causing a public nuisance, British Transport Police said.
Eyewitnesses at St Pancras International station on Friday evening said they spotted a protester on the tracks, shouting about Brexit and waving an St George's flag.
A BTP spokesman said: "The charges relate to an incident where a man was on top of railway infrastructure, resulting in a number of rail services from St Pancras International needing to be suspended as a safety precaution."
He was remanded in custody to appear before Westminster Magistrates' Court on Monday.
Assistant Chief Constable Sean O'Callaghan said: "Friday evening's incident was extremely challenging and I would like to thank the public for their patience whilst a number of specialist teams responded.
"This was a fast-paced inquiry and I am pleased that a man has now been charged in connection."
Several services on the route had to be scrapped following the incident, which began on Friday evening and ended when a suspect was arrested around 12 hours later.
The incident happened on the day the UK was originally due to leave the EU, and followed a day of Brexit protests in Westminster.
