REUTERS/Brendan McDermid LONDON — Former Democrat Presidential nominee Hillary Clinton says Brits who supported Brexit in last year's referendum on European Union membership "voted against modern Britain."

Clinton, who was defeated by Donald Trump in last year's US election, told the Sunday Times in an interview: "They voted against modern Britain and the EU, believing that somehow this would be good for their small village. It made no sense.

"The same thing played out in my race, but I didn’t think we were so vulnerable. But it turned out we were wrong — in part because the Russians played a much bigger role."

Clinton said that last June's Brexit vote "should have been a bigger alarm" for her campaign and said: "It was some of the same people working for Trump, advocating for him," who campaigned for Britain to leave the European Union.

"How, in democracies like ours [can] people believe nonsense and lies on the side of buses about how much money the UK government paid to the EU? How did we let this happen?” Clinton said, referencing Vote Leave's infamous claim that £350 million-a-week was sent to the EU and could be spent on the NHS.

Clinton said that the tactic used by both the Brexit campaign and the Trump campaign was to "tell a really horrible lie over and over again, keep people off balance and make them think that this will, if not make their lives better, make them feel better."

The former Secretary State also called for a UK investigation into Cambridge Analytica, the big data company whose involvement in both the Brexit vote and the Trump campaign have been called into question.

"I hope the UK are investigating," she said. "You know they were involved in the Kenya elections and Brexit, and are the subject of congressional and special counsel inquiries. The question to be asked is: how did they, the Russians and the Trump campaign converge?"
