A 61-year-old man has been charged with assaulting West Suffolk MP Matt Hancock.
The alleged assault reportedly took place on the London Underground at about 8.40am on Tuesday.
Geza Tarjanyi, 61, from Leyland in Lancashire, will appear in court next month, accused of common assault and two public order offences, British Transport Police said.
Officers were called to reports of a man being "harassed and assaulted" at the station next the House of Commons.
Tarjanyi was released on bail to appear at Westminster Magistrates’ Court on February 22.
After the arrest, a spokesman for the former health secretary said: “Both Transport for London staff and the British Transport Police were fantastic and the man has since been arrested.”
He added that “this sort of behaviour is a rare occurrence” and stressed the “importance of shutting down baseless misinformation which causes so much harm”.
Mr Hancock was stripped of the Conservative whip after he appeared in the hit ITV show I'm A Celebrity... Get Me Out of Here.
In December the MP for West Suffolk announced he would not be standing at the next general election.
