About Robert Lambert

Robert Lambert is a British former undercover police officer and academic. He served in the controversial Special Demonstration Squad and posed as a left-wing animal rights activist from 1983 to 1988. While undercover, he had sexual relationships with four women, fathering a child with one of them, all of whom were unaware of his true identity. The child and the child's mother needed psychiatric treatment after discovering Lambert's identity much later, and both were awarded damages against the police. He has also been accused of involvement in an arson attack while undercover, which Lambert denies, as well as giving false evidence in court.
