THE BILLIONAIRE tycoon George Soros has given another £400,000 to an anti-Brexit group in a bid to keep Britain inside the EU.

The Hungarian-born philanthropist has responded to criticism of his donations by handing hundreds of thousands more to Best For Britain – who want to overturn the referendum decision.

He had previously pledged to match the total received by the pressure group from a crowd-funding campaign – which has garnered around £100,000.

But the 87-year-old investor – known as the man who “broke the Bank of England” – has gone further and funnelled another £400,000 into Best For Britain’s coffers in the wake of the Cambridge Analytica data scandal.

The donation, revealed by BuzzFeed, has been made through his Open Society Foundations whose president told the website: “In the past fortnight fresh evidence has emerged suggesting Leave campaigns misled voters about their spending and used a questionable data company to target voters on social media.

“The Open Society Foundations believe that British citizens have a right to know whether the UK’s democratic process was undermined during the referendum vote.”

Patrick Gaspard added: “We are therefore backing Best for Britain’s call for an investigation into the matter and donating a further £400,000 to their campaign for a meaningful vote on the final Brexit proposal.”

Mr Soros has previously defended his donations by claiming it is his “love for Britain” which is driving his crusade against Brexit.

He said the UK’s historic vote to leave was a “tragic mistake” and also denied accusations he was “undermining democracy”.

The billionaire also said “allowing a referendum on membership was a fatal error”, and that Brexit is a “lose-lose proposition both for Britain and for Europe”.

But Mr Soros was blasted by Brexiteer politicians and told to “stay out of British politics”.

A furious Lord Lamont, the Tory chancellor plunged into a recession by George Soros’ mammoth bet against the Pound 25 years ago, told him to “stick to finance”.

The Tory peer said: “It seems very perverse and odd for the Soros foundation, which exists to promote democracy, to seek to undermine democracy in this way.”

And ex-Tory leader Iain Duncan Smith demanded Best for Britain hand back the £400,000.
