Commons Speaker Sir Lindsay Hoyle has told how he lies awake at night fearing he will get yet another phone call telling him an MP has been murdered.
The veteran politician was close friends with Conservative MP Sir David Amess, 69, who was stabbed to death during a constituency meeting a year ago today.
He was also deeply affected by the killing of Labour MP Jo Cox, 41, in 2016 when he was Deputy Speaker and her party colleague.
