Several women disrupted Philip Hammond's speech at an annual banquet in London's Mansion House by shouting slogans through loudspeakers. Video footage showed Mark Field, a foreign office minister, physically removing one of the women from the room by grabbing her neck. Field later apologized, but Prime Minister Theresa May's spokeswoman announced on Friday that Field had been suspended pending an investigation. Field explained to ITV that he acted out of concerns for security. "In the current situation, I felt the need to take decisive 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 speech by Philip Hammond in London. The Labour Party's spokeswoman for women and equalities, Dawn Butler, called for Field to be suspended or fired immediately, describing the incident as "horrific." Greenpeace, the environmental campaign group, stated that they organized the protest in the financial district of London, accusing the finance industry of funding climate change and criticizing the finance ministry for attempting to weaken government efforts to address it." Rebecca Newsom, Head of Politics at Greenpeace UK, condemned Field's reaction to the demonstrator, calling it violent and shocking. The City of London Corporation is reassessing its security procedures following the incident at Mansion House on Thursday night.
