Classical singing group Collabro won this year's Britain Got Talent, following an impressive final performance on the show. This will mean that the five-piece will scoop a cool £250,000 and will perform at the Royal Variety Performance. Lucy Kay and Bars & Melody finished second and third respectively.

Speaking before the event kicked off, judge Simon Cowell tweeted that this was one of the best finals he'd taken part in, claiming that it was open for anyone to win. The night also saw Cheryl Cole and Tine Tempah perform their new single, 'Crazy Stupid Love', while Little Mix and series 3 winners Diversity performed 'Salute'.

Here's Collabro's winning performance. Has nobody mentioned the fact that Collabro sounds like one of the X-Men?
