Last year's Britain's Got Talent live shows got off to a rather awkward start when Ant McPartlin suffered a "heavy fall" live on-air.The TV presenter took a tumble following the show's opening dance number - which was performed by 2009 winners, London-based dance group Diversity, fronted by Dancing On Ice judge, Ashley Banjo. As the dance was coming to an end Ant and his co-host Declan Donnelly made their way centre stage to introduce the first act, when Ant slipped into the air, landing on his back before dancer Ashley helped him to his feet.
