The Labour Party leader Sir Keir Starmer is hoping to become the UK's next prime minister. He first won his seat in Parliament in 2015 after a successful career working as a human rights lawyer and then being appointed the UK's Director of Public Prosecutions. He was previously rumoured to be the inspiration for the handsome but stuffy character Mark Darcy, a lawyer and love interest in the novel Bridget Jones's Diary, written by Helen Fielding. The author has denied the link, however interest in Mr Starmer has started to grow as polls suggest he could get the keys to 10 Downing Street. Steve Smith travels through the 'Starmersphere' speaking to friends, colleagues and critics finding out who he is and what he stands for.
