Britain's re-elected Prime Minister, Boris Johnson, says the largest Conservative majority in a poll since the 1980s proves the British people want Brexit pushed through.

In a jubilant speech to party supporters, Mr Johnson stressed the United Kingdom would leave the European Union by January 31.

"This election means that getting Brexit done is now the irrefutable, irresistible, unarguable decision of the British people," Mr Johnson said.

"And this election I think we put an end to all those little, miserable threats of a second referendum."

With all results declared, the Conservatives won 365 seats and the main opposition Labour Party 203.

Declaration of the final seat was delayed until Friday, after bad weather in the Cornwall seat of St Ives prevented a helicopter from picking up voting papers from the Isles of Scilly — 45 kilometres off the coast.
