Currently the majority of Eurostar services to and from London are cancelled due to a last minute strike by Eurotunnel Workers, which started at 11am.
Eurostar are currently unsure how whether this action will extend beyond today.
This is in the French forum as it must be French workers to strike with little or no notice. They are wanting a discretionary bonus 3,000 Euro. EuroTunnel have offered a third of that.
This also affects the vehicle shuttles which are also suspended, with pax diverted to ferry services.
