David Cameron gave a short victory speech after his audience with the Queen to form a new government.
His Tory party has won an overall majority in the House of Commons, marking and end to the coalition that was formed in 2010, and sparking the resignations of three of his rival party leaders: Labour’s Ed Miliband, coalition partner Nick Clegg and Ukip leader Nigel Farage.
Mr Cameron recognised the huge shift in Britain’s politics after the SNP swept to a huge victory in Scotland, all but wiping out the other parties.
On Scotland, Mr Cameron pledged “to create the strongest devolved government anywhere in the world”.
He pledged to “implement as fast as I can the devolution that all parties agreed for Wales, Scotland and Northern Ireland”.
“With our plans, the governments of these nations will become more powerful with wider responsibilities,” he said.
“We must ensure that we bring our country together… we will govern as a party of one nation, one United Kingdom.”
He also promised to “deliver that in/out referendum on our future in Europe”.
In a nod to one of his pre-elections slogans, he added: “We can make Britain a place where a good life is in reach for everyone who is willing to work and do the right thing.”
