Harry Potter star Emma Watson is the one most Brits believe is their country’s ‘Greatest Female Ambassador’.The 17-year old, who plays the muggle-born witch Hermione Granger in the hit movie adaptations of the Harry Potter novels, has beat out the likes of older and more well-known faces such as Kate Moss, Keira Knightley and Victoria Beckham.The poll was conducted by Top of the Pops magazine, and editor Peter Hart said that it was Watson’s combination of beauty and brains that were the qualities that sealed the deal.“A good ambassador needs brains and beauty, not just bags of cash,” The Sun quoted him, as saying.Coming in close on Hermione’s heels in second place was Oscar nominee Keira Knightley, followed by singer Lily Allen in third spot.Fourth place on the list went to pregnant singer Charlotte Church.Rounding off the top five was another pregnant beauty, former glamour model Jordan.And, while Victoria Beckham aka Posh Spice only managed eighth place, Kate Moss and Girls Aloud’s Sarah Harding found themselves at the bottom of the poll.
