Kemi Badenoch has become the latest candidate to be knocked out of the Conservative leadership race.
In the fourth round of voting by Tory MPs, the contenders received the following votes:
Another vote will take place on Wednesday, which will leave just two candidates remaining.
They will then face a summer of campaigning and hustings before a vote by the wider party membership, with the winner expected to be announced on 5 September.
The remaining runners will not face each other in a debate that had been planned by Sky News for tonight after Mr Sunak and Ms Truss refused to take part.
Conservative MPs are said to be concerned about the damage the previous debates have done to the image of the party after exposing disagreements and splits between the leading candidates.
The leadership contest was triggered after Boris Johnson announced he would be leaving Downing Street after an avalanche of ministerial resignations over his handling of the Chris Pincher scandal.
He will remain as prime minister until his successor has been named.
