With the shock of the US elections finally subsiding, all eyes will be on Washington DC for a very different reason this weekend. The 66th Miss World pageant will be taking place at the MGM National Harbor in Oxon Hill (just south of the capital, in Maryland) and millions will be tuned in to see who will succeed Mireia Lalaguna of Spain.

Some of our favourite stars first caught the world's attention in beauty pageants, using these victories as a springboard for careers in their respective fields, so don't be surprised if you see the next Oprah Winfrey during the talent segment of the competition. Now worth an estimated $3bn (£2bn), the 62-year-old media mogul and chat-show queen's first taste of fame was at the Miss Black Tennessee pageant in 1972 where she took home the crown.

Before you decide who you are backing, here's a rundown of the most successful pageant queens to ever boast a tiara and emblazoned sash.
