And he was not paying National Insurance. The genius of it was that no one in Britain realised that Beckham had become a tax exile. Instead, the public believed that he was a global success who paid his taxes in Britain.
"Partly that was due to sightings of him in London. Legally, he could visit Britain 90 days a year and after five years the annual limit would increase to 120 days."
