Commuters are facing a 40 minute delay if they are travelling from Ebbsfleet station in Dartford to Stratford and St Pancras. 

The delay is due to overruning engineering works. 

All lines are disrupted at Ebbsfleet, with Southeastern posting online: "Due to earlier emergency engineering works between Ebbsfleet International and St Pancras International all lines are disrupted.

"The power had to be switched off to both tunnels between St Pancras International and Stratford International to allow an inspection and repair to be made. Both tunnels are now open, however there may be delays and alterations to some trains."

Service is expected to return to normal this morning.
