The 56-year-old politician presents himself as an amiable northern everyman who prefers T-shirts to a suit and tie and spends spare time playing soccer or spinning 1990s tunes during DJ battles. He’s also an experienced politician whose career has taken him from high-level government jobs to the mayoralty of Greater Manchester. He's now expected to challenge Prime Minister Keir Starmer after winning a seat in Parliament in a special election he hailed as a “turning point” for U.K. politics. (Produced by Joana Mateus)
