Operation Midland was a criminal investigation which the London Metropolitan Police carried out between November 2014 and March 2016 in response to false allegations of historic child abuse made by Carl Beech.

The Elm Guest House was a hotel in Rocks Lane, near Barnes Common in southwest London. In a list produced by convicted fraudster Chris Fay, several prominent British men were alleged to have engaged in sexual abuse and child grooming at the Guest House in the late 1970s and early 1980s. Labour MP Tom Watson, having heard testimony from Carl Beech, suggested in an October 2012 statement to the House of Commons that a paedophile network which had existed at this time may have brought children to parties at the private residence.
