Who’s Who at the Royal Wedding

The guests have streamed in to Westminster Abbey to watch Prince William marry Kate Middleton. Who got the biggest cheers from the throngs outside? Prime Minister David Cameron was a hit, as was Elton John—and, of course, Princes William and Harry, who arrived looking dapper in full military regalia. Prince Charles and Camilla have arrived, as has the queen; no glimpse of Kate yet, but the BBC notes that her dress designer was likely spotted yesterday and could be Sarah Burton, creative director of Alexander McQueen.

The guests are a mixture of royalty (more than 50 from the UK, roughly 40 from foreign monarchies), political figures, and celebrities, many of whom are wearing very large hats. See more in the gallery. Watch this spot for more updates or click here for full coverage. (More royal wedding stories.)
