Ten candidates have secured the necessary nominations to enter the first round of voting in the Tory leadership race in the UK.
The candidates are: Boris Johnson, Jeremy Hunt, Michael Gove, Dominic Raab, Sajid Javid, Matt Hancock, Mark Harper, Esther McVey, Rory Stewart and Andrea Leadsom.
The candidates to replace Theresa May as British prime minister launched their campaigns today promising to solve the turmoil of Brexit and taking shots at frontrunner Boris Johnson.
On Thursday morning the first of the votes will take place. By lunchtime Thursday, any candidate who has 16 votes or fewer will be eliminated.
The following week the process speeds up, with elimination votes on 18, 19 and 20 June.
Those rounds will eventually leave just two candidates in the race, at which point they must move from convincing MPs to convincing the wider membership of the Conservative party - an estimated 120,000 people.
It is those party members who will cast the final ballot on who should win, not just the party leadership, but leadership of the country.
Mrs May stepped down as leader of the Conservative Party last Friday, having failed three times to win parliament's support for a European Union divorce deal that was supposed to address Britain's biggest political crisis in a generation.
Nominations to replace her had to be submitted today, and each of the candidates needed to secure support from at least eight of the Conservatives' 300-plus elected lawmakers.
All the public campaign launches set out domestic agendas, but it was Brexit that dominated, with overt and thinly veiled digs at former foreign minister Johnson.
"If I get through, which I am sure I will actually, to the final two against Mr Johnson, this is what I will say to him: 'Mr Johnson, whatever you do, don’t pull out'," said environment minister Michael Gove, who scuppered Johnson’s 2016 leadership bid by pulling his support at the last moment to run himself.
"I know you have before, and I know you may not believe in your heart that you can do it, but the Conservative Party membership deserve a choice'."

Nearly all promised that they could solve the Brexit conundrum - which eluded Mrs May in three years of EU talks - in just three months, between the new leader being chosen at the end of July and the current exit date of 31 October.
"From my conversations with European leaders, it is clear to me there is a deal to be done; they want us to come up with proposals," current foreign minister Jeremy Hunt said.
He warned that unless the issue was sorted the party would be annihilated in an election and socialist Labour leader Jeremy Corbyn would take power.
Dominic Raab, who quit as Brexit minister over Mrs May's divorce deal, said he too could secure a new agreement but promised that the United Kingdom would leave the EU on 31 October, even if that meant reverting to basic World Trade Organisation trade terms.
"I'm the Brexiteer that you can rely on," he said.
Others, including Mr Johnson, have made the same promise to leave on time, even if it means giving up on a deal with the EU to smooth the transition.
The differences between the candidates reflect Conservative disunity on the issue, which has meant that, three years after the United Kingdom voted by 52% to 48% to quit the EU, it remains unclear how, when or even whether it will indeed leave.
Mr Johnson is not only the bookmakers' clear favourite but, according to polls, the most popular with the 160,000 party members who will ultimately make the choice.
