The pro-Brexit activist James Goddard has been handed a suspended prison sentence and banned from travelling near Parliament for verbally abusing MP Anna Soubry.
Goddard admitted to calling the former Conservative MP a "Nazi" and a "traitor" outside the Houses of Parliament in December and January.
He has been sentenced to eight weeks in prison – suspended – and handed a five year restraining order that bans him from contacting the Change UK leader.
The 30-year-old was also banned from entering an area around Parliament that includes Parliament Square, College Green and Downing Street and told to carry out 200 hours of unpaid work.
Goddard will pay Ms Soubry £200 in compensation and another £200 to a Lithuanian police officer over a separate racially motivated offence.
The self-styled 'yellow vest' protester was sentenced alongside Brian Philips, who was handed a four week suspended sentence and a restraining order.
Lynette Woodrow from Crown Prosecution Service said: “Goddard and Phillips crossed the line between legitimate protest and causing outright alarm and distress.”
“They were not interested in a debate but set out to intimidate, antagonise and bully Anna Soubry,” she added.
Following the sentencing Ms Soubry tweeted: “Another £200 for the Jo Cox Foundation #MoreInCommon #HopeNotHate.”
In her victim impact statement she said she was “really intimidated” and “very shaken” by the verbal assault.
“In a democracy, people have a right to peaceful lawful protest. No-one has the right to intimidate and abuse anyone,” she said.
