An undercover officer who allegedly "spied" on the Lawrence family disclosed details concerning the separation of Stephen Lawrence's mother and father, Doreen and Neville.
The officer - known as N81 - reportedly "touched on personal details" concerning the family to the Special Demonstrations Squad (SDS) during the 1998 inquiry into Stephen Lawrence's death, according to the Ellison report.
Neville Lawrence labelled the claims as "disgusting", telling the Daily Mail: "It's unbelievable. They have mocked everything we have done, telling us to our faces that they are listening and things will change, and all the time laughing behind our backs.
"I think they are actually worse than criminals because these officers get paid with taxpayers' money for what they do."
