Several women disrupted Philip Hammond's speech at an annual banquet in London's Mansion House by shouting slogans through loudspeakers, causing a brief interruption. Video footage captured foreign office minister Mark Field physically removing one of the women from the room by holding her by the back of her neck. Field later apologized for his actions, but Prime Minister Theresa May's spokeswoman announced his suspension pending an investigation. Field explained to ITV that his response was driven by concerns for security. "In the present circumstances, I believed it was necessary to take decisive action to eliminate the threat to the safety of those in attendance," he stated. No response was given by his office to a request for comment from Reuters. Tory MP for Cities of London & Westminster, @MarkFieldUK, can be 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, an environmental organization, stated that they had orchestrated the protest in the financial district of the capital, accusing the finance industry of financing climate change and criticizing the finance ministry for attempting to weaken government efforts to address it. Field's reaction towards the demonstrator was condemned by Rebecca Newsom, the Head of Politics at Greenpeace UK, who expressed shock and concern over the violent behavior displayed. The City of London Corporation is reevaluating its security procedures following the incident at Mansion House on Thursday night. A spokesperson stated that they are investigating the breach and will make changes for future events.
