This is the BBC news with Fiona MacDonald. Boris Johnson will take over as British Prime Minister today as the country is facing its biggest political crisis in decades over Brexit. Mr. Johnson, who won the leadership of the governing Conservative Party on Tuesday, has already been in discussions about who to appoint to his cabinet. This report from Nick Eardley. What will Boris Johnson be like his Prime Minister? Some relish him entering number ten. Some dread it completely. But this afternoon, around four o'clock, when he speaks to the country for the first time in his new job, we will get more of an idea of what he intends to do with the power he has long coveted. Inevitably, his greatest challenge will be Brexit, delivering his promise of leaving the European Union by the end of October without breaking his party. But before all that, Theresa May will take part in her final Prime Minister's questions in the Commons. She will also deliver a farewell statement from Downing Street before going to Buckingham Palace to formally resign.
