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.
We’ve now seen a few of the auditions, which will continue until April 19, followed by five semi-finals and a live final on May 31.
Here are the 10 early favourites.

5. Vinnie McKee
Glaswegian Vinnie McKee's rendition of The Proclaimers' '(I'm Gonna Be) 500 Miles' earned him a golden buzzer from Simon Cowell. The holiday park entertainer is a 10/1 shot for the title. | ITV

6. Hear Our Voice
Also priced at 10/1 are Hear Our Voice, a choir mainly made up of Sub Post Masters directly affected by the Horizon Post Office Scandal. They impressed at their first audition with a performance of 'Falling Down' by Will and the People. | ITV

Amanda pressed her golden buzzer for 11-year-old guitarist Olly Pearson's medley of ‘Highway to Hell’ by AC/DC, ‘Jump’ by Van Halen and ‘Don’t Stop Me Now’ by Queen. He's already in the semi-finals, and is 10/1 to go all the way. | Canva/Getty Images
