First broadcast in 2007 and hosted by Ant & Dec, Britain’s Got Talent invited performers to impress a panel of judges with a place on the bill for the Royal Variety Performance up for grabs.
Previous winners, who also get a £250,000 payout, have included the likes of Diversity, Lost Voice Guy, Paul Potts and George Sampson.
The judges for the 18th series - the first starting in February instead of April - are Simon Cowell, Amanda Holden, Alesha Dixon and Bruno Tonioli.
The auditions are now at an advanced stage, with the first of five semi-finals getting underway in less than two weeks, ahead of the live grand final on May 31.
Here are the 10 favourites to win.
