The Metropolitan Police has been forced by a judicial ruling to disclose the identities of two undercover police officers who allegedly had relationships with women activists in groups they infiltrated.
A spokesman for the Met said: "In compliance with the order of Mr Justice Bean the MPS has confirmed in its defence that Jim Boyling and Bob Lambert were undercover police officers."
The women are among a number of people who want compensation for emotional trauma allegedly caused by officers infiltrating environmental activist groups.
Their claims for deceit, assault, negligence and misfeasance in public office arise out of long-term and intimate sexual relationships they had with four men who - unknown to them - were members of the Special Demonstration Squad (SDS), between 1987 and 2007.
Mr Justice Bean issued an ultimatum which forced the Met to disclose the names in its defence in order to be able to answer to the claims and had the force not done so within 28 days it would have been taken to admit them.
