Liz Truss has emerged as the clear favourite to succeed Boris Johnson as leader of the ruling Conservative party and UK prime minister, using her political experience to pull ahead of challenger Rishi Sunak.

Sunak helped to spark the contest after resigning in opposition to a series of government scandals, prompting others to follow and Johnson to step down.

But although considered a better public speaker, he has come under fire for clinging to fiscal orthodoxy to tackle the economic crisis and hamstrung by his image as a wealthy technocrat.
