The Prodigy and the Chemical Brothers are to headline the second stage at this year's V Festival.
They will join main stage headliners Scissor Sisters and Franz Ferdinand at the event over the weekend of August 20-21.
The Prodigy play Weston Park, Staffordshire; on Saturday and Hylands Park, Chelmsford; on Sunday, and the Chemical Brothers vice versa. It will be the Chemical Brothers' only UK festival performance of the year.
Festival director Bob Angus said: "We pride ourselves on putting on an unbeatable live music experience and V Festival 2005 will not disappoint."
