Five police forces are investigating claims of historical child sexual abuse involving former PM Sir Edward Heath. Wiltshire Police halted an inquiry into a brothel keeper in the 1990s after she said Sir Edward was involved in child sexual abuse. Claims made by the brothel keeper, Myra Ling Ling Forde, that Sir Edward was a client, meant that she had left herself open to prosecution. However, the case against her was allegedly discontinued between 1990 and 1995. She was later convicted of controlling prostitutes, [and] jailed for six years after a trial that included allegations that she had supplied children as young as 13 to her clients. The Independent Police Complaints Commission said on Monday that it would look at whether Wiltshire officers failed to pursue allegations of child abuse made against Sir Edward, who was Conservative prime minister from 1970 to 1974. A retired detective has alleged claims were made in the 1990s but not followed up. Kent Police told the BBC it had received a report on Tuesday of a sexual assault having been committed in east Kent in the 1960s [that] named Sir Edward Heath in connection with the allegation. Meanwhile, Labour MP Tom Watson said he had referred two allegations of child sexual abuse by Sir Edward to the police since 2012. He said police had confirmed that at least one of those allegations was being investigated.
