Kasabian and Snow Patrol are to join the reformed Stone Roses as headliners for this year's T In The Park.

The Scottish festival will also feature appearances by New Order and superstar DJ David Guetta, as well as Jessie J and Tinie Tempah.

Organisers of the event at Balado, near Kinross, added a further 20 names to the line-up today, including Brit Award-winning star Emeli Sande who took this year's Critics' Choice prize.

The Stone Roses appearances are among the biggest draws of the summer and the band's hometown gigs in Manchester sold out within hours. They subsequently announced a number of festival performances - their first with guitarist John Squire since he left the band in 1995, prior to the group falling apart the following year.

Around 85,000 people will attend the event each day for this year's 18th annual festival which takes place from July 6 to 8.

Appearances from Noel Gallagher's High Flying Birds, Florence and the Machine, The Maccabees and The Vaccines have already been announced.

The final batch of tickets for the event go on sale at 9am next Wednesday.

Geoff Ellis, festival director, said: "It's one of the strongest launches we've had and it's a very diverse line-up. It's important to have something for everyone because we're a very small country, and to sell 85,000 tickets has us on a par with the biggest festivals worldwide.
