Hillary Clinton has launched an incendiary attack on Donald Trump, claiming that he colluded with Russian efforts to stop her from winning the US Presidency.

Speaking at a tech conference in California’s Silicon Valley, the former Secretary of State received huge applause as she made a series of stark claims – including her belief that the ‘vast majority’ of news about her on Facebook was fake.

She also openly admitted that she believed Trump had ‘colluded’ with Russia in a bid to become President.

She told the assembled crowd: ‘I take responsibility for every decision I made but that is not why I lost.

’The Russians in my opinion – and based on intelligence and counterintelligence people I have spoken to – could not have known best how to weaponise that information unless they had been guided by a specific group of people. By Americans.’

Mrs Clinton then turned her attentions to Facebook, and claimed that ‘low information voters’ had been persuaded by reading a slew of fake news that had been spread on Facebook.

’Some people were sucked in. Some people stayed home. Some people voted Trump’, she alleged – before claiming that ‘1,000 Russian agents’ had been involved in attempts to make her lose.

She also referenced the ‘Pizzagate’ scandal as an example of fake news – after conspiracy theorists claimed that she was running a prostitution ring from a New York pizza parlour.

She added: ‘You had counties that had voted for Obama and were not particularly keen about voting for Trump, but worried that I was going to jail, worried that I was, you know, running a child trafficking operation in the basement of a pizzeria.

‘The kind of things that were in WikiLeaks – you laugh, but people were obsessing over this stuff. Obsessing over it.’
