Below is the text of the statement made by John Bercow, the Speaker of the House of Commons, on 21 February 2019.
I have a short statement to make about PC Keith Palmer, who tragically died on 22 March 2017. PC Palmer was nothing short of a hero, in the way in which he ran towards danger to ensure the safety of us all on that day. He paid the ultimate price for doing the job that he loved, and we owe him a profound debt of gratitude for his bravery. Yesterday afternoon, the Police Memorial Trust placed a permanent memorial to PC Palmer at Carriage Gates. Not only will it serve as a lasting tribute to his dedication and courage, but it will ensure that visitors to Parliament never forget his sacrifice and heroism.
