Former Manchester United star Ryan Giggs went on trial Monday accused of submitting his former girlfriend to a "litany of abuse" during a coercive and "toxic" relationship, in a case that has upended his managerial career. The 48-year-old, who until recently served as coach of the Wales national team, has pleaded not guilty to the charges, which carry a maximum jail term of five years. The jury trial opened at a crown court in Manchester on Monday morning, presided over by judge Hilary Manley. She said it is expected to last two weeks. Giggs entered the court building looking grave-faced, flanked by his legal team.
