British prime minister Theresa May presided over a meeting of her cabinet on Tuesday following her resignation as Conservative party leader last week.
The meeting came as the campaign to replace her as leader - and as prime minister - intensified.
Ten present and former ministers are competing for the post.
A number of contenders shrugged off questions from reporters as they arrived in Downing St for the meeting, and were similarly tight-lipped after they left.
The front runner is former foreign secretary Boris Johnson.
Other leading contenders include the current foreign secretary Jeremy Hunt, former Brexit secretary Michael Gove, home secretary Sajid Javid, health secretary Matt Hancock, and former Commons leader Andrea Leadsom.
In votes starting Thursday, Conservative lawmakers will narrow the field down to two.
Those two will then be put to a vote of Conservative party members nationwide.
