British lawmakers debating the future of Brexit were interrupted Monday by a group of semi-naked protesters who stormed the public gallery of the House of Commons to protest climate change, Sky News reports. “Parliament just got a little bit more nuts!” MP James Heappey wrote on Twitter alongside a photo of the 11 protesters, two of whom reportedly wore full grey body paint and elephant masks. One protester, clad in a leather thong, reportedly glued his hand to a surface in the public gallery. The group, Extinction Rebellion, said that they aimed to “call attention to the ‘elephant in the room’—climate and ecological crisis.” Meanwhile, the assembled lawmakers were debating alternative Brexit plans after British Prime Minister Theresa May’s compromise deal was defeated for a third time.
