How can we better protect our public figures?

Police have declared the fatal stabbing of the Conservative MP, Sir David Amess, to be a terrorist incident. Sir David was attacked yesterday while holding a surgery for constituents at Leigh-on-Sea in Essex. Police forces are expected to contact all 648 MPs over the course of Saturday after the Home Secretary ordered an immediate review of their security arrangements. Martha Kearney speaks to Jade Botterill, who has experienced constituency surgeries in her work for Yvette Cooper MP, and gets the thoughts of both Harriet Harman MP and the former Chief Constable of Greater Manchester Police, Sir Peter Fahy. Following that, Nick Robinson speaks to Sir Bernard Jenkin MP and former Home Secretary, Jacqui Smith, about the tradition of MPs meeting their constituents face to face.
