The former cop who MI6 fears has leaked damning secrets about Prince Andrew's friendship with Jeffrey Epstein to the Russians has broken his silence to say he has hours of footage taken from the billionaire paedophile's Florida mansion.

John Mark Dougan, a former US deputy police chief, had access to the investigation into the billionaire paedophile before he fled the FBI and is now living in Moscow. 

And asked by MailOnline about what information he has, Dougan said: 'Do I have dirt on Prince Andrew? I have lots of things.

'But I'm not a Kremlin agent and I did not share any materials with the Russian Government. I don't intend to blackmail anyone with my information. It's against my principles.'

In a statement, Dougan said the Epstein files are encrypted. The codes to open them are held by friends all over the world 'as an insurance policy'.
