Is the Trump dossier fake?
The leaked alleged 'dirty dossier', describing salacious sex acts carried out by Donald Trump in the presidential suit of a Moscow hotel, has led to a political storm. It is so outrageous it has been described by some as something out of a spy novel. Frederick Forsyth, a spy author who worked for MI6 for 20 years, thinks the dossier is unbelievable, arguing Trump would have to be a "congenital idiot". Christopher Andrew is an official historian of MI5, he thinks the dossier could be real and says that there is evidence that Russia are behind it. (Image: Spy man in silhouette, credit: Getty Images)
