Radiohead, Arctic Monkeys and Kings of Leon have been confirmed as the headline acts at the U.K.'s twinned Reading and Leeds Festivals.

The festivals will held at Little Johns Farm, Reading and Bramham Park, Leeds, over England’s August Bank Holiday weekend (Aug. 28-Aug.30).

Other bands confirmed for the two shows include Kaiser Chiefs, The Prodigy, Yeah Yeah Yeahs. Vampire Weekend, Placebo, Fall Out Boy, Bloc Party, Deftones, Funeral For A Friend, Maximo Park, Ian Brown, Friendly Fires, Gallows, The Courteeners, White Lies, Gossip, Florence and the Machine and Glasvegas.

The big news, however, is Radiohead making its debut headline performance at Reading and Leeds Festival. The shows will be Radiohead’s only U.K. festival appearance of 2009. The Oxford-based band last played Reading Festival in 1994 and will perform at Leeds on Saturday Aug. 29 then close the Reading leg of the festival the following night.

King of Leon’s headline appearances on Friday Aug.28 at Reading and Sunday Aug. 30 in Leeds also mark the band’s only English festival dates and will form their final U.K. shows of 2009.

Arctic Monkeys headline slot, meanwhile, will be the band’s first U.K. live dates since December 2007. The band headlines Leeds on Friday Aug. 28 and Reading the following night.

To combat touting, festival organisers Festival Republic have also today (March 30) announced that they have signed a deal with secondary ticketing company Viagogo to become the official secondary ticketing and ticket exchange partner of the Reading, Leeds and Latitude Festivals. The Latitude festival in Southwold, Suffolk, with headliners Pet Shop Boys, Grace Jones and Nick Cave & the Bad Seeds takes place July 16-19.

Marking the first time that a major music festival has signed a partnership with a secondary ticketing partner, Viagogo will allow fans to legitimately buy and sell tickets in a secure online environment. A physical pick-up point will also exist at the Leeds and Latitude festival sites and Reading town centre to allow fans to personally collect their tickets.

Melvin Benn, Managing Director of Festival Republic, said in a statement: “There were some disastrous ticketing issues last year leaving many fans disappointed after ‘buying’ non-existent resale tickets. A number of rouge ticketing websites sprung up offering fans tickets to our festivals that they did not posses. We have therefore agreed to work with Viagogo as the recommended and only official ticket exchange for the Reading, Leeds, and Latitude festivals. If fans use other ticket exchanges or buy from unauthorized agents they risk being defrauded and not getting their festival tickets.”

Tickets for Reading and Leeds Festival go on sale March 30 at 7pm (U.K. time) with weekend tickets costing £175.00 plus booking fee. Day tickets will be available at £70.00 each plus booking fee.
