Scotland Yard has launched a full investigation into allegations that Conservative politicians were members of a paedophile ring which abused British children in care the 1980s.
Operation Fernbridge will centre on the alleged historic sexual abuse of children at Elm Guest House, in Rocks Lane, a suburban street in Barnes, southwest London.
Residents of a nearby care home run by Richmond Council claim they were sexually assaulted at the property by a network of prominent individuals, including Tory MPs.
The allegations are one of several lines of inquiry being considered by specialist detectives as a result of information supplied to them by Labour MP Tom Watson.
In a surprise intervention in the Commons in October, Watson - who alleged widespread phone hacking at the News of the World before police began a new inquiry - urged Scotland Yard to reopen the evidence file on Peter Righton, a former childcare consultant who was convicted of importing illegal homosexual pornography in 1992.
