Street dance group Diversity has been crowned the winner of this year’s Britain’s Got Talent TV show in a shock victory over favourite Susan Boyle.

The 11-strong group, aged 12 to 25, from Essex fell to the floor and cried in surprise when told of the win.

Member Ashley Banjo, 20, said winning the contest had “changed our lives”.

The group defied bookmaker’s predictions to win the £100,000 prize and the chance to perform at the Royal Variety Show in December.

‘Utter perfection’

Diversity is made up of three sets of brothers and four friends and was only formed in 2007.

Still shocked about the victory, choreographer Banjo said: “When you said our name, honestly I’m going to wake up in a minute.”

He also thanked everyone who had voted for the group.

After the performance, which included a cheeky reference to the judges’ buzzers, judge Simon Cowell said: “If I had to give marks on that, that is the only performance tonight I would want to give a 10 to.

“There was not a step out of place, it was sheer and utter perfection.”

Fellow judge Amanda Holden said Banjo’s choreography was “second to none” and that Diversity had blown rival dance troupe Flawless “out of the water”.

Throughout the competition the group had wowed the audience and received glowing comments from the judges, but the group was sixth favourite to win going into the final.
