American indie rock band The National, Scottish singer Paolo Nutini and '90s favourites Suede have been announced as the headliners for this year's Latitude Festival.

The three acts were unveiled this evening as tickets for the festival at Henham Park, near Southwold, went on sale.

Amongst the other music names to be unveiled were Paloma Faith, Foals and KT Tunstall, while the popular comedy tent will welcome Jon Richardson, Jason Byrne and Omid Djalili.

The festival returns for its sixth instalment from Thursday, July 14 to Sunday, July 17, and chosen to headline the first night are indie-rockers The National.

The five-piece from Ohio headlined the festival's Word Arena last year, but go a step further this year by closing the main stage on the first night.

On Saturday it will be the turn of Paolo Nutini. The Scottish singer shot to fame in 2006 with his debut album These Streets and was one of the headliners in the festival's first year.

Closing the festival this year on the Sunday night will be Suede, who scored huge success in the 1990s, winning the Mercury Music award for their self-titled debut album in 1993. They have reformed and will close the festival on Sunday night.

Other music acts announced included 2010 Mercury nominees Foals, Villagers and I Am Kloot, as well as solo singing stars Paloma Faith and KT Tunstall.

The comedy tent is always very popular at Latitude and this year the line-up includes Omid Djalili, Phill Jupitus, Jon Richardson, Jason Byrne and Richard Herring. There will also be the Edinburgh Comedy Award's best newcomer Roisin Conaty.

The film and music arena will also play host to a special question and answer session with Steve Coogan and Rob Brydon.

The poetry tent welcomes Jo Shapcott, Simon Armitage, Tim Key and Saul Williams, while the literary arena will see Alan Hollinghurst, Alexei Sayle, Dave Gorman and Marcus Brigstocke. Theatre performances will be provided by Battersea Arts Centre and Hammersmith Lyric.

Tickets to the festival went on sale this evening, with a weekend pass from �170 and day ticket from �70.

This marks a �15 increase in ticket price from last year with organisers promising a number of changes including a second bridge across the lake, a larger arena and entrance, more security, and larger poetry and literary arenas. However, the total capacity has not gone up.

Festival founder and managing director of Festival Republic Melvin Benn called this year's programme 'utterly exceptional'.

He said: 'I am extremely proud of what has been achieved over the past five glorious years of Latitude. We've been listening to our loyal fans and this year, for our sixth edition, we are making some changes to the site which will further enhance everyone's enjoyment of their favourite festival weekend.'
