Moment Boris Johnson and Carrie Symonds realise they’ve won the election

They had bottles of Budweiser, sweets, a pot of tea and the most important addition: pet dog Dilyn, who had his own chair.

How do you celebrate if you’re the prime minister finding out you’re winning the biggest majority in over 30 years?

By literally jumping for joy it seems.

Boris Johnson, 55, was pictured with girlfriend Carrie Symonds, 31, watching the results on TV in his study at 10 Downing Street.

They had bottles of Budweiser, sweets, a pot of tea and the most important addition: pet dog Dilyn, who had his own chair.

As seats declared for the Tories, the prime minister was out of his seat with jacket flailing with the force of his jump, while next to him his partner also punched the air.

Another picture taken from the study shows Carrie watching the results from the floor, apparently too nervous to keep in her seat, while Boris appears tired as the night goes on.

Boris Johnson secured an 80-seat majority after decimating the traditional Labour heartlands, where many people voted Tory for the very first time.

Some areas including Bishop Auckland in the North East had never elected a Conservative MP before Thursday’s General Election.

Speaking to supporters in Tony Blair’s old constituency of Sedgefield, County Durham, Mr Johnson expressed his gratitude to voters for ‘changing the political landscape’.

He said: ‘I want to thank you, all of you, for the trust that you have placed in us in the Conservative Party and in me, and I know how difficult it was, it can be to make that kind of decision.

‘And I can imagine people’s pencil’s hovering over the ballot paper and wavering before coming down for us and the Conservatives, and I know that people may have been breaking the voting habits of generations to vote for us.

‘And I want the people of the North East to know that we in the Conservative Party and I will repay your trust – and everything that we do, everything that I do as your Prime Minister, will be devoted to repaying that trust.’
