Thousands of passengers have been told to “postpone” their Eurostar train journeys to and from Paris with the firm expecting cancellations and delays.
Eurostar said the disruption was “due to part of the track being temporarily closed on the French network”.
It advised passengers to keep an eye on the Eurostar website and app for further updates.
Nine trains between London and Paris have been cancelled for Monday while a further 17 have been delayed, according to the Eurostar website.
