Several women disrupted Philip Hammond's speech at an annual banquet in London's Mansion House by shouting slogans through loudspeakers. Video footage showed Foreign Office minister Mark Field physically removing one of the women from the room by grabbing her by the back of her neck. Field later apologized for his actions, but Prime Minister Theresa May's spokeswoman announced that he has been suspended from his duties pending an investigation. Field explained that his response was driven by security concerns. "In the current situation, I believed it was necessary to take decisive action to eliminate the threat to the safety of those in attendance," he stated. His office did not respond to a Reuters request for comment. Tory MP Mark Field 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, describing the incident as "horrific." Greenpeace, the environmental campaign group, stated that they had organized the protest in the financial district of London, accusing the finance industry of financing climate change and criticizing the finance ministry for attempting to weaken government efforts to address it. Rebecca Newsom, Head of Politics at Greenpeace UK, criticized Field's reaction to the demonstrator, stating that she sees no justification for the violent behavior displayed. The City of London Corporation is re-evaluating its security procedures following the incident at Mansion House on Thursday night, with a spokesman stating that they are investigating the breach and will review arrangements for future events.
