The operator’s trains have not called at Ashford or Ebbsfleet since March 2020 after all services were suspended due to the Covid-19 pandemic.
The company confirmed services carrying passengers between London St Pancras and Europe via the Channel Tunnel would not stop at the two Kent stations during 2023. They added it would not be able to "make any commitment for another two to three years".
The firm cited "financial factors" and the "post-Brexit border situation" as reasons for the postponement.
