A Tory MP was told "I hope you get a horrible, painful cancer" in an abusive email which he read out in Parliament on the sixth anniversary of Jo Cox's murder.
Peter Bone condemned the "sick" element of society that still threatens MPs from across the divide after the Labour MP's death.
He said she was "a happy, young Labour MP who was clearly going to make a mark on this place", and also mentioned the murder of his "dear friend" Conservative David Amess.
