The U.K.'s Labour Party called on Theresa May to sack a foreign office minister after he was filmed forcefully grabbing a female climate protester at a black tie banquet in the City of London.

In this longer version of the video, you can see the woman apparently posing no immediate threat as she passes behind Mark Field. He marches her out of the room by her neck. I wasn’t there, so I can’t say she didn’t pose a risk, but it looks heavy handed. pic.twitter.com/zX2BtcPW4t — Paul Brand (@PaulBrandITV) June 20, 2019

Mark Field can be seen pushing the woman against a pillar then grabbing her by the back of the neck and marching her out of the room. Greenpeace confirmed she was part of a group of its activists who disrupted the annual Mansion House event in central London — a fixture of the financial calendar — and called Field's actions "assault."

Field apologized for "grabbing" the woman, saying he was concerned she may have been armed, according to the BBC. He said he reacted "instinctively" and had referred himself to the Cabinet Office for an investigation.

Shadow Women and Equalities Minister Dawn Butler said Field's actions were “horrific.”

“Conservative Foreign Office Minister Mark Field violently grabs a woman as she protests about climate change at the bankers’ banquet,” she said on Twitter.

“This appears to be assault. He must be immediately suspended or sacked. Due to violence against women.”

The incident is also embarrassing for Foreign Secretary Jeremy Hunt, who will launch the second phase of his Conservative leadership campaign tomorrow after he secured a place on the run-off ballot to be put to party members.

As well as being a minister in Hunt’s department, Field has backed his campaign to be the next U.K. prime minister.

The Mansion House banquet, which was addressed by Chancellor Philip Hammond and Bank of England Governor Mark Carney, was disrupted by dozens of female Greenpeace protesters wearing red dresses and sashes with "climate emergency" written on them.

A Downing Street spokesperson did not respond to a request for comment.
