Professor Green described Hackney as "home" and said it was "the place where it all started".

"Hackney is a great place, so events like this and the Olympics will help showcase the borough in a positive light," BBC quoted the rapper as saying.

"I can't wait to be a part of such an amazing event," he added.

"This is a concert in the heart of east London and we will use it as an opportunity to shine a light on and celebrate the young people of east London too," said Radio 1's Event Director for 2012, Jason Carter, adding the event would be a massive celebration.

Registration for tickets will begin on Monday and close on March 19; registrations can be confirmed online and those with confirmed registrations can apply for tickets either online or by telephone.
