Andy Burnham has said he will "give this his all" in his first speech as Britain's new prime minister. He has been officially appointed after a meeting with King Charles in Buckingham Palace. Mr Burnham served in Labour governments two decades ago, before leaving Westminster in 2017 to become mayor of Greater Manchester. The 56-year-old said he has "unfinished business" on the national stage, and has promised to provide "more breathing room" for the country. Olly Barratt reports from London.
