Several women disrupted Philip Hammond's speech at an annual banquet in London's Mansion House by shouting slogans through loudspeakers. Foreign office minister Mark Field was seen on video grabbing one of the women by the back of her neck and escorting her out of the room. He later apologized, but Prime Minister Theresa May's spokeswoman announced on Friday that Field has been suspended pending an investigation. Field explained to ITV that his actions were motivated by concerns for security. "In the current situation, I believed it was necessary to take quick action to eliminate the threat to the safety of those present," he stated. His office did not respond to a request for comment from Reuters. Tory MP for Cities of London & Westminster @MarkFieldUK was seen grabbing a Greenpeace protester who disrupted a Philip Hammond speech in London. The Labour Party's spokeswoman for women and equalities Dawn Butler called for Field to be suspended or fired immediately, calling the incident "horrific." Greenpeace organized the protest in London's financial district, accusing the finance industry of funding climate change and the finance ministry of trying to weaken government efforts to address it. Rebecca Newsom, Head of Politics at Greenpeace UK, expressed disapproval of Field's reaction to the demonstrator, calling it violent and concerning. The City of London Corporation is reevaluating its security measures following the incident at Mansion House on Thursday.
