A man has been arrested on suspicion of assaulting former health secretary Matt Hancock on the London Underground.

The MP who appeared on I’m A Celebrity… Get Me Out Of Here! is understood to have been unhurt in Tuesday’s incident which began at Westminster station before continuing on a Tube train.

A spokesman for Mr Hancock, who represents West Suffolk, said it was an “unpleasant encounter”.

British Transport Police said they received a report of a man being “assaulted and harassed” at the station next to the House of Commons before 9am.

“A 61-year-old man has been arrested on suspicion of common assault and a public order offence and remains in custody,” the force said.

Inquiries are ongoing.

Mr Hancock’s spokesman said: “Both Transport for London staff and the British Transport Police were fantastic.”

He added “this sort of behaviour is a rare occurrence” and stressed the “importance of shutting down baseless misinformation which causes so much harm”.

“Matt wants to put on record his thanks to TfL and the British Transport Police for their extraordinary work,” the spokesman added.

Video circulating online showed a transport worker supporting the MP throughout much of the incident.

At one stage during the exchange, a man challenges Mr Hancock over lockdown and brands him a "murderer".

After getting off the train, he appears to follow the MP, who turns and accuses him of pushing him.

Mr Hancock, 44, was health secretary when the coronavirus pandemic struck and was a key figure in the lockdown restrictions and vaccine rollout that followed.

He resigned after leaked CCTV image showed him kissing an adviser in his office, in breach of his own social distancing guidance.

Mr Hancock angered colleagues and constituents by jetting to the Australian jungle to appear on the reality show but won some sympathy from TV voters to come third.

Having been stripped of the Conservative whip over the appearance, he said he would not contest his seat at the next election when he will step down.
