Boris Johnson's Brexit guru Dominic Cummings tore into Remainer MPs and journalists today after the Tories swept to a landslide victory, boasting: 'You f***ed it up'.

The Vote Leave mastermind, now a senior aide to the Prime Minister, tore into his political opponents after the Tory landslide that ensured that the UK will leave the EU in January after years of wrangling.

He was typically blunt after the Conservatives racked up a stunning tally of 365 seats in the first December election for nearly a century.

The win also raises questions about his on future in the heart of the Tory machine, now that his dream of Brexit appears certain to be realised.

Speaking in Westminster after Boris Johnson had triumphantly returned to Number 10, he said he could not take any credit for the win.

'After the shock of the referendum MPs and journalists should have taken a deep breath and had a lot of self-reflection of why they misunderstood what was going on in the country,' he said.

'But instead a lot of people just doubled down on their own ideas and f****d it up even more.

'That's why something like this happens against expectations.

'All these better than average educated Remainer campaigner types who have waved around for eight weeks, for the last four months and didn't understand what was going on and didn't understand they were driving everyone mad.'

Mr Cummings continued: 'Hopefully now they'll learn because it's not good for the country, the whole dynamic to carry on.

'MPs need to reflect, the media needs to reflect and they need to realise that the conversations they have in London are a million miles away from reality.'

A triumphant Mr Johnson ordered Remainers calling for a second referendum to 'put a sock in it' today as he hailed his staggering election landslide.

In a speech in Westminster, Mr Johnson said the election rout had finally settled the Brexit issue, saying pressing ahead was now the 'irresistible, unquestionable decision of the British people'

After laying waste to Labour's 'red wall' of Leave-backing strongholds, the PM said he had been given a 'powerful' vote of confidence by the British people and would work 'night and day' to repay their trust.

He said the election rout had finally settled the Brexit issue, saying pressing ahead was now the 'irresistible, unquestionable decision of the British people'.

And in a stark message to those who have been pushing for a rerun of the 2016 Brexit contest, he said: 'That's it. Put a sock in the megaphone.'

He joked: 'Let's get Brexit done. But first, let's get breakfast done.'
