In the UK, candidates for the Tory leadership have clashed on how Brexit should be delivered.
Five of the six contenders took part in a special hustings in Westminster in front of journalists today.
Former Foreign Secretary Boris Johnson did not participate.
But his campaign continued to gain ground with the support of Matt Hancock, which came as a blow to Environment Secretary Michael Gove - who had been looking for his endorsement.
At the hustings, Rory Stewart said he had the necessary 33 backers to make it through the second round of voting in the contest "if they do what they say".
The International Development Secretary suggested he was the one to beat Mr Johnson - and accused the former foreign secretary of making different promises to different MPs.
Home Secretary Sajid Javid also said he was "extremely confident" of getting the required 33 votes.
Former Brexit secretary Dominic Raab used his hustings slot to describe the event as an "essential gauntlet" to be run, in a dig at Mr Johnson's non-appearance.
Around 160,000 Tory members across the country will decide the next prime minister from the final two candidates chosen by Conservative MPs.
With Mr Johnson more than 70 votes ahead of his nearest rival Jeremy Hunt in the first round of voting, the contest now appears to be about who will face him in the final two.
The 20 MPs who backed Matt Hancock in the first round of voting will now have to choose their new candidate, and not all will follow the Health Secretary to Mr Johnson's camp.
Former Hancock supporter and East Renfrewshire MP Paul Masterton said he would now back Rory Stewart.
