Boris Johnson back as PM isn't practical - Dominic Raab

Boris Johnson is flying back to the UK from a holiday in the Caribbean with suggestions he could be about to put his hat in the ring to run for office again.

His former deputy Dominic Raab, who has pledged his support for Rishi Sunak, says he can't back Mr Johnson as prime minister while the Partygate inquiry continues.

Mr Sunak is yet to formally announce if he intends to enter the race to be PM for a second time.
