THE Met spied on 17 justice campaigns for murder victims and those who died following police contact over 35 years, it was revealed yesterday.

Among those who were monitored are the family of Jean Charles de Menezes, who was shot dead by police in July 2005.

The disclosure was made by Derbyshire Chief Constable Mick Creedon, who is leading Operation Herne examining the conduct of undercover officers from Scotland Yard’s Special Demonstration Squad (SDS).
