Ant & Dec returned to present the main show on ITV, while Stephen Mulhern returned to present spin - off show Britain's Got More Talent on ITV2 . Simon Cowell and Amanda Holden returned as judges . Alesha Dixon and David Walliams joined the judging panel, replacing Michael McIntyre and David Hasselhoff . Carmen Electra served as a guest judge for the London auditions in Holden's absence . The series was won by dancing dog act Ashleigh and Pudsey, with opera duo Jonathan and Charlotte coming second . Welsh choir Only Boys Aloud came third . This was the first series since series 4 where Cowell was present at the auditions after only being present at the live shows in series 5 . </P> <P> From this series onwards, the winner's cash prize was increased from £ 100,000 to £ 500,000, and the number of judges still remained at four . The series was supposed to premiere on 14 April, as mid-April is when each series usually begins, but it was brought forward three weeks to premiere on 24 March--the same night as the launch of The Voice UK on BBC One . Many media outlets saw this move as a deliberate attempt by ITV to create a "TV ratings war" with the BBC . </P>
