Foreign Office Minister Mark Field has been suspended from his post after he was filmed forcefully grabbing a climate change protester who gatecrashed a back-tie dinner.

A spokesperson for Prime Minister Theresa May said she seen the footage of the incident and “found it very concerning”.

The Tory MP was facing calls to be sacked following the confrontation in which he was seen to physically frogmarch the female protester from the event at London’s Mansion House, with Labour branding the video “horrific”.

The environmental activist involved Janet Barker, who lives on a farm in Wales, said she would not press charges but suggested he should go on an anger management course.
