Northern Ireland band Snow Patrol will make a triumphant return to Latitude this summer - after being forced to cancel last-minute in 2019.
Festival organisers say the 2020 line-up is the "biggest yet" as they announced further music, comedy, and arts performers.
Haim, The Chemical Brothers and Liam Gallagher had already been announced as the headliners for the Obelisk Arena with Bill Bailey taking the top spot in the comedy tent.
Latitude will take place at Henham Park from July 16 to 19.
Snow Patrol were due to headline the Suffolk festival in 2019 but illness forced them to cancel - with Welsh rockers Stereophonics taking their place.
Instead, they'll take the Sunday lunchtime slot on the Obelisk stage to help mark their 25th year in the music industry.
The band said they were "gutted" to have missed out last year.
"Snow Patrol are thrilled to perform our Reworked set (featuring 14 musicians no less) as special guests. Having played the first ever Latitude in 2006 we were gutted that injury forced us to cancel our headline slot last year. Thank you Latitude for giving us another chance to make it up."
Among the other performers announced on Thursday were La Roux, Kate Tempest and Brits Critic's Choice nominee Mahalia.
Meanwhile Simon Amstell will return to Latitude's comedy arena, Jenny Eclair and Judith Holder will broadcast a live version of their Older and Wider podcast, and Mark Kermode will be in the Music and Film Arena.
