"The connectivity that is the heart of globalisation can be exploited by states with hostile intent to further their aims.[…] The risks at stake are profound and represent a fundamental threat to our sovereignty."
Alex Younger, head of MI6, December, 2016

"It's not MI6's job to warn of internal threats. It was a very strange speech. Was it one branch of the intelligence services sending a shot across the bows of another? Or was it pointed at Theresa May's government? Does she know something she's not telling us?"
Senior intelligence analyst, April 2017

In June 2013, a young American postgraduate called Sophie was passing through London when she called up the boss of a firm where she'd previously interned. The company, SCL Elections, went on to be bought by Robert Mercer, a secretive hedge fund billionaire, renamed Cambridge Analytica, and achieved a certain notoriety as the data analytics firm that played a role in both Trump and Brexit campaigns. But all of this was still to come. London in 2013 was still basking in the afterglow of the Olympics. Britain had not yet Brexited. The world had not yet turned.
