An alleged victim of the Westminster paedophile abuse scandal claims he saw a Tory MP strangle a young boy to death at a sex party.

Police are investigating three killings allegedly linked to the VIP paedophile network.

Scotland Yard have confirmed it has launched a probe, Operation Midland, connected to investigations into allegations of sex abuse from the 1970s and 1980s as well as a "possible homicide".

"Detectives from the child abuse investigation command are working closely with colleagues from the Homicide and Serious Crime Command concerning this information," the Metropolitan Police in a statement.

A key witness known as "Nick" has provided hours of video testimony, according to a report in the Sunday Mirror.

Nick has claimed that in the 1980s he was in the room when a 12-year-old boy was strangled to death by a Tory MP. Eighteen months later he told police that a second boy was killed by two men in front of another MP. The third murder was of a 10-year-old child being deliberately run down by a car in the 1970s.

Nick stated that his own father offered him to the paedophile network of MPs and VIPs at an apartment in Dolphin Square, Westminster near Parliament, as well as at other London locations.

According to his evidence, he and other boys aged between 10 to 14 were raped at "abuse parties", where they were plied with alcohol.

Nick gave an account of being driven to an orgy with the alleged strangulation victim.

He said: "We looked at each other and saw the fear in each other's eyes. We said nothing.

"I knew we were being taken somewhere to be sexually abused by powerful men.

"But I had no idea of the true horror of what was about to happen."

The witness, who is now in his 40s, described the Conservative minister who allegedly strangled the boy. "The MP was particularly nasty, even among the group of people who sexually abused me and others," he told the Sunday Mirror.

"I still find it difficult to talk about these incidents after all these years."

Both ex-MPs Nick referred to are said to be alive and the witness has assisted the Met in creating e-fit photos of the three young children who are reported to have been killed.

"There will be other people who know about the punishment and abuse carried out by this group. Drivers of the cars who took the boys to venues, staff at the venues. Perhaps they can now come forward," Nick told the investigative newspaper Exaro.

A second witness has come forward corroborating some of the information handed over to the police.
