Irish singer Sinead O'connor insists she has known about allegations of a Vip paedophile ring at the heart of the British Establishment "for years".

Investigators are probing claims of a huge child abuse conspiracy involving some British politicians and other public figures dating back to the 1960s.

It is alleged a dossier naming some of those involved was destroyed during a cover-up, and O'Connor - a veteran campaigner against child abuse - has now spoken out to insist the paedophile ring was an open secret in Westminster and those involved have been protected by a "hundred-year silence order" which buries the evidence.

She tells Q magazine, "(I've been) educating myself, offstage... (I've known about it) for years. Everyone knows about that... I didn't used to believe in Satan and now I f**king do."
