Boris Johnson is preparing for power as he awaits the widely expected confirmation that he has defeated Jeremy Hunt in the battle to become the UK's next prime minister.
As the overwhelming favourite to be crowned Conservative Party leader, Mr Johnson is poised to unveil an ambitious domestic policy agenda looking beyond Brexit in his victory speech.
Last night, Boris Johnson was plotting with his inner circle as Theresa May held a farewell party for ministers and Conservative MPs in 10 Downing Street.
This is what is expected to happen in the coming days:
- The result will be announced at Westminster's QE2 conference centre at 11.40am today following an overnight count. Watch decision live on Sky News from 11.30am
- The winner – almost certainly Mr Johnson – will then make a victory speech
- Theresa May will take part in her final Prime Minister's Questions on Wednesday
- She will then head to Buckingham Palace to offer her resignation to the Queen
- Her Majesty will meet the new Tory leader and invite him to form a new government
- Traditionally, the new PM will make a statement in Downing Street before stepping into Number 10
- Appointments to the cabinet and ministerial team are expected on Thursday, and the reshuffle could continue into Friday
Voting among the Tories' 165,000 eligible members closed at 5pm on Monday.
The declaration of the result marks the finale of a month-long battle between Mr Johnson and Jeremy Hunt, which has included a TV debate, 16 hustings across the UK, interviews, campaign visits and photo opportunities.
Welcoming Mr Johnson's expected victory, leading supporter Jacob Rees-Mogg told Sky News: "I think Boris will be good for the country because he'll deliver on his promise to leave EU and he'll do that by 31 October.

"He'll be good for the Conservative Party as he has the electoral stardust that makes him attractive and a unifying figure across the country."
Ultimately, it has been Mr Johnson's pledge to leave the EU by Halloween "do or die" that has given him the edge over Mr Hunt, in a leadership contest dominated by Brexit.
Jonathan Isaby, editor of Brexit Central, told Sky News: "The Tory grassroots have been looking for someone who believes in Brexit and also someone who is deeply optimistic about Brexit.
"Optimism is something people have been desperately crying out for."
But in his victory speech, Mr Johnson is expected to look beyond Brexit and unveil a domestic policy agenda including social care, school funding and boosting business in the regions.
Allies of the former foreign secretary claim he will emphasise "unity" and the need to bring the Conservative Party and the country back together after the divisions of Brexit.
But he faces the threat of a collision course with parliament over a no-deal Brexit.
