Controversial activist Lee Jasper has been blasted for a tastleless tweet about the armed mugging of Tony Blair's daughter.
Kathryn Blair was held at gunpoint in Marylebone where she was walking with her boyfriend and a group of friends. She escaped unharmed.
Jasper, who was an adviser to former London mayor Ken Livingstone, tweeted: "Quoting one of me heroes I say 'Chickens coming home to roost' #ViolenceBegetsViolence"
It generated a backlash from other Twitter-users, including a Labour MP:
But Jasper was defiant:
Scotland Yard confirmed an incident involving two male suspects with a gun took place in Ivor Place, Marylebone, at 8.30pm on Monday night.
A spokesman said: "The victims were a man and a woman; the suspects were two males."
