Following the incident, where the train was backed up and David pulled from the track he was then taken to St. Thomas's Hospital for checks.
David Ruffley has been the Conservative MP for Bury St Edmunds, Suffolk, since 1997.
A British Transport Police source told The Sun:
"It was not believed to be an accident. Witnesses said he deliberately tried to jump in front of the train. At this stage it appears to have been a half-hearted attempt to kill himself.If this was as appears a suicide attempt then the Conservative Party and his family must ensure he gets all the help he needs to get him through this extremely difficult time.
There are many organisations who can help.
Let's hope David has a speedy recovery.
