On the night before the 1911 census, women's suffragist Emily Davison spent the night in a broom cupboard in the back of the crypt in order to be able to give her address as the House of Commons, despite not being allowed to stand for Parliament or vote. A plaque was unofficially placed in the cupboard to commemorate this in around 1991 by the late Tony Benn MP. He put the plaque in place with his own hands and proudly showed it to visitors. He later installed a second plaque for a purpose which is now lost but the Palace authorities required him to remove it. The screw holes are still visible.
