A former bodyguard of Sir Paul McCartney and Heather Mills has leaped to the defence of the ex-beatle's estranged wife, insisting the public are "too down" on her. Sean Ghent, hired by MCCartney last year (May06) following the couple's shock split, claims Mills has been unfairly vilified in her native Britain. Ghent, 44, says, "She is one of the most impressive people I have ever met and has been a huge influence on me. I want people to understand some of that. "I don't get why the British public are so down on her. She's made a success of herself against all odds. "She just wants to influence, change and inspire people."
