A FORMER British intelligence officer identified as being the source of the incendiary dossier about US President-elect Donald Trump has reportedly gone into hiding.

Christopher Steele, who runs London-based Orbis Business Intelligence, apparently left his Surrey home on Wednesday night with no indication of when he would be coming back.

The dossier, which has yet to be authenticated, professes to show that Russia held damaging information about his business interests and footage of him using prostitutes in Moscow.
