"It’s a superb piece of work, wonderfully done and essential reading for anyone who cares for his country. Amazing research and brilliantly collated." John Le Carré

"Collusion is so essential and ... I wish everyone who is skeptical that Russia has leverage over Trump would read it ... Invaluable." The New York Times

MOSCOW, July 1987. Real-estate tycoon Donald Trump visits Soviet Russia for the first time at the invitation of the government.

LONDON, December 2016. Luke Harding meets former MI6 officer Christopher Steele to discuss the president-elect’s connections with Russia. Harding follows two leads; money and sex.

WASHINGTON, January 2017. Steele’s explosive dossier alleges that the Kremlin has been 'cultivating, supporting, and assisting' Trump for years and that they have compromising information about him. Trump responds on twitter, 'FAKE NEWS.'

In Collusion, award-winning journalist Luke Harding reveals the true nature of Trump’s decades-long relationship with Russia and presents the gripping inside story of the dossier. It features exclusive new material and draws on sources from the intelligence community.

Harding tells an astonishing story of offshore money, sketchy real-estate deals, a Miss Universe Pageant, mobsters, money laundering, hacking and Kremlin espionage. He shines a light on powerful Russian players like Aras Agalarov, Natalia Veselnitskaya and Sergey Kislyak, whose motivations and instructions may have come from Vladimir Putin himself. The special prosecutor, Robert Mueller, has already indicted several of the American protagonists, including Trump’s campaign manager, Paul Manafort. More charges are likely as the crisis engulfs Trump’s administration.

This book gets to the heart of the biggest political scandal of the modern era. Russia is reshaping the world order to its advantage: this is something that should trouble us all.
