"Policing was rocked by the fallout from a Scotland Yard inquiry, Operation Midland, into claims establishment figures were involved in child sexual abuse in the 1970s and 1980s.
A report in November 2016 castigated the Metropolitan police for being duped by false claims from a complainant given the name “Nick”. In that case, police chiefs were among the last to realise their inquiry, which wrongly targeted establishment figures, was an error.
Heath died in 2005, aged 89, meaning there can be no trial, making the resolution of the allegations complicated. At the end of their investigation, police are planning a report assessing whether the evidence gathered would have been sufficient to charge him."

That was over a year ago, and no such assessment has been forthcoming.
