Former prime minister Boris Johnson on Saturday returned to Britain from a holiday to launch an audacious political comeback, as Conservative leadership rival Rishi Sunak reached the minimum threshold to contest the UK's top job.

The former prime minister cut short a family holiday in the Dominican Republic as the race to replace Liz Truss gathered momentum.

The former prime minister has flown back to the UK, with many in his party tipping him to return to power after Liz Truss dramatically quit.

Mr Johnson was ousted by his colleagues following a slew of scandals.

UK Trade Minister Conor Burns sacked over ‘serious misconduct’ claim. Liz Truss fired Burns over a complaint about his behavior at Tory party conference.

Less than a month into Liz Truss’ turbulent time as U.K. prime minister, her top colleagues are publicly questioning her approach.

It’s not just her disastrous mini-budget that’s had Britain’s prime minister rowing back.
