Kate Middleton tipped to top poll of Beautiful Royals

Britain's Kate Middleton is set to top a poll to find the most beautiful royal.

The gorgeous brunette - whose place in the monarchy will be cemented when she marries Prince William on April 29 - is up against her fiance's late mother, Princess Diana, and her future brother-in-law Prince Harry in the online poll.

Kate faces competition from royals across the globe including Princess Grace of Monaco and Queen Rania of Jordan.

The poll does have a flipside however, with users also voting for the ugliest member of a royal family, with historical figure Henry VIII and ex-wife of Prince Andrew, Sarah Ferguson, both in the running.

Greg Hodge, managing director of dating website BeautifulPeople.com - which is conducting the poll - said: "We've opened up the voting so that subjects in every nation can judge past and present monarchs, as well as duchesses, princes and princesses in waiting - in a history-making beauty contest.

"In any other century we'd have our heads chopped off for treason. We're not anti-monarchy, we're just anti ugly people."

Anyone can vote for their most beautiful royal on the company's website between now and April 18.
