PR-savvy and now finally a knight - Beckham always knew how to turn on the charm

A sporting icon courted by prime ministers past and present, newly knighted Sir David Beckham is renowned for being extremely media savvy.

Never more so than when I interviewed him for Sky News at the 2008 Beijing Olympics, after he took part in the closing ceremony having played a key role in London's winning bid to host the 2012 Games. Speaking about Sir Alex Ferguson in the interview, canny Sir Becks heaped praise on his old boss in our interview.

By 2008 he was playing for LA Galaxy in the US. But despite his canny, PR-savvy answers in my interview, I saw him work the room that night in Beijing and glad-hand relentlessly.

He gave every interview asked of him and turned on the charm on behalf of UK PLC to everyone present. For politicians and prime ministers, sportsmen and women like Beckham are pure gold.

David Cameron was also a fan and was photographed sitting alongside Becks at the London Games. When "Goldenballs.
