BBC Radio 1's Hackney Weekend, the biggest music event of the 2012 Cultural Olympiad, is set to take place on June 23 and June 24, with 100,000 tickets available. More than 25 acts have been confirmed for the two-day event, which will feature six stages of music at Hackney Marshes, London.

Ed Sheeran, Professor Green and Jessie J, Leona Lewis, Plan B, Tinie Tempah, Chase & Status, David Guetta, Dappy, Will.i.am, Labrinth, Jack White, Emeli Sande and Lana Del Rey and Florence & The Machine are some of the artists who are going to perform at the event.

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.

The Hackney Weekend is held once a year by BBC Radio 1 at different locations within the United Kingdom each time. It is the biggest free-ticketed music event in Europe and always includes a host of new artists.
