Prime Minister Boris Johnson has secured a whopping 80-seat majority after the final result capped off a Tory landslide this afternoon.
The result for St Ives in Cornwall was declared shortly before 3pm – hours after 649 of the 650 seats up for grabs had been taken.
It had been delayed after stormy conditions overnight grounded a helicopter and boats from carrying the ballot boxes.
It wasn't until this morning the boxes could be transported from the outer islands of the Isles of Scilly to the main island of St Mary's.
And shortly before 3pm it was announced the Tories had held the seat, confirming the Conservatives had bagged a total of 365 seats.
Johnson then stood outside 10 Downing St this afternoon, hours after his party's thrashing of Labour forced Jeremy Corbyn to quit.
He said: "Good afternoon, this morning I went to Buckingham Palace and I am forming a new Government and on Monday MPs will arrive at Westminster to form a new Parliament.
"I'm proud to say that members of our new one nation Government, a people's government, will set out from constituencies that have never returned a Conservative MP for 100 years.
"And yes, they will have an overwhelming mandate from this election to get Brexit done and we will honour that mandate by January 31.
"In this moment of national resolution I want to speak directly to those who made it possible, and to those who voted for us for the first time and those whose pencils may have wavered over the ballot and who heard the voices of their parents and grandparents whispering anxiously in their ears, I say thank you for the trust you have placed in us and in me.
"We will work around the clock to repay your trust and to deliver on your priorities with a Parliament that works for you and then I want to speak also to those who did not vote for us or for me and who wanted and perhaps still want to remain in the EU.
"I want you to know that we in this one nation Conservative government will never ignore your good and positive feelings of warmth and sympathy towards the other nations of Europe.
"Because now is the moment, precisely, as we leave the EU, to let those natural feelings find renewed expression in building a new partnership, which is one of the great projects for next year.
"As we work together with the EU, as friends and sovereign equals, tackling climate change and terrorism, in building academic and scientific co-operation, redoubling our trading relationship, I frankly urge everyone, on either side of what are, after three and a half years, after all an increasingly arid argument, I urge everyone to find closure and let the healing begin.
"Because I believe, in fact I know because I've heard it loud and clear from every corner of the country, that the overwhelming priority of the British people now is that we should focus above all on the NHS.
"That simple and beautiful idea that represents the best of our country with the biggest ever cash boost, 50,000 more nurses, 40 new hospitals as well as providing better schools, safer streets and in the next few weeks and months we will be bringing forward proposals to transform this country with better infrastructure, better education, better technology.
"If you asked yourselves 'what is this new government going to do, what's he going to do with his extraordinary majority'. I will tell you that is what we are going to do.
"We are going to unite and level up.
"Unite and level up, bringing together the whole of this incredible United Kingdom: England, Scotland, Wales, Northern Ireland.
"Together, taking us forward, unleashing the potential of the whole country.
"Delivering opportunity across the entire nation.
"And since I know, that after five weeks, frankly, of electioneering, this country deserves a break from wrangling, a break from politics, and a permanent break from talking about Brexit.
"I want everyone to go about their Christmas preparations, happy and secure in the knowledge that here, in this people's government, the work is now being stepped up to make 2020 a year of prosperity, and growth and hope, and to deliver a Parliament that works for the people.
"Thank you all very much, and Happy Christmas."
Johnson's thrashing of Labour saw Corbyn's party slump to just 203 seats in its worst performance since 1935, with huge swathes of Britain turning from red to blue.
Earlier, in his first victory speech, Johnson spoke to declare the that the victory meant the Tories now represent "everyone" and promised Brexit will finally get done.
Giving his speech in London, Johnson said: "We did it - we pulled it off, didn't we?
"We broke the gridlock, we ended the deadlock, we smashed the road block."
Johnson added: "And I will make it my mission to work night and day, flat out to prove that you were right in voting for me this time, and to earn your support in the future.
"And I say to you that in this election your voice has been heard, and about time too.
"Because we politicians have squandered the last three years, three and a half years in squabbles - we've even been arguing about arguing, and arguing about the tone of our arguments.
"I will put an end to all that nonsense and we will get Brexit done on time by the January 31 - no ifs, no buts, no maybes.
"Leaving the European Union as one United Kingdom, taking back control of our laws, borders, money, our trade, immigration system, delivering on the democratic mandate of the people."
Johnson repeated his pledges to deliver 50,000 more nurses, 50 million more GP surgery appointments, 20,000 more police officers and 40 new hospitals.
And he said: "You, the people of this country, voted to be carbon neutral in this election, you voted to be carbon neutral by 2050 and we'll do it.
"You also voted to be Corbyn neutral by Christmas by the way and we'll do that too.
"You voted for all these things, and it is now this People's Government, it's our solemn duty to deliver on each and every one of those commitments."
Closing his speech, Mr Johnson said: "Let's unite this country, let's spread opportunity to every corner of the UK. And let's get Brexit done.
"But first, my friends, let's get breakfast done too."The Tory landslide overnight prompted Corbyn to announce that he will not lead Labour into another election after his party suffered humiliation, but will stay on for a few more months.
Lib Dem leader Jo Swinson also lost her seat to the SNP and quit as party leader. Sir Ed Davey and Baroness Sal Brinton will become joint acting leaders ahead of a leadership contest next year.
The success of the Scottish nationalists and of nationalist parties in Northern Ireland could provide Mr Johnson with another challenge on top of Brexit as it suggests opposition to leaving the EU is hardening there.
But Tory supporters are unlikely to be worrying about that on Friday after witnessing their party take seat after seat in Labour's heartlands, including some they had never held before.
Johnson was on course to finish with over 43% of the popular vote, the highest for a Tory leader since Margaret Thatcher's victory in 1979 and around the same as Tony Blair's in 1997.
Among the first world leaders to congratulate Johnson was Donald Trump.
The US President tweeted his congratulations, adding that the UK and US will "now be free to strike a massive new trade deal after Brexit".
Corbyn, who had sought to exploit Mr Trump's support for the PM during the election campaign, admitted it had been a "very disappointing" night.
He announced he would call it a day as leader as he was re-elected in his London seat.
He said he would discuss with the party how to ensure there was a "process of reflection ".
