Rishi Sunak's won the day, set to become Britain's youngest Prime Minister.

The 42-year-old says he's humbled and honoured to have his colleagues support, and is promising stability and unity.

Boris Johnson had been plotting a comeback, but he ultimately decided against running.

He claims to have had 102 backers, although only 57 MPs publicly declared their support.

Political commentator Iain Dale told Kate Hawkesby those who were backing Johnson feel let down, after he led them up the garden path.

He says some of them were made to look very stupid for supporting him.
