Stereophonics have sold millions of albums

Also confirmed on the bill are Chemical Brothers, Primal Scream, Groove Armada, Badly Drawn Boy, Supergrass, Starsailor, Ian Brown, Turin Brakes, Beta Band, Elbow and the Stereo MCs.

The festival, which is in its seventh year, was the first to offer concerts with the first day's line-up at one venue moving to another site to play the next day.

Album charts

Stereophonics lead singer Kelly Jones said: "We haven't played an English festival in for nearly two years so headlining V2002 will be a great way of finishing touring the JEEP (Just Enough Education to Perform) album."

Badly Drawn Boy won the 2000 Mercury prize

The band's last album has remained in the UK album charts for 47 weeks and in three years they have sold six million records.

Bob Angus, festival director at the Essex event, said: "V2001 was the best V yet, and we're looking to make V2002 even bigger.

"To get Stereophonics and Travis as headliners is a major coup for us. They're two of the UK's biggest-selling bands of recent years, hardly moving out of the Top 10 in the album charts."

Primal Scream: Indie favourites

Simon Moran, festival director in Weston Park, said: "We've still got a lot of acts to announce, but I'm proud to say that the line-up is already looking very satisfying.

"We've got some major-selling bands heading the bill, and some big talent of the future coming in earlier in the bill."

Last year Coldplay, the Red Hot Chilli Peppers and Texas headlined the event, with more than 50,000 fans attending each site.
