They’re the first wave of big names announced for the festival, which takes place in Suffolk in England.
Speaking about headlining the event, George Ezra said: ‘It’s no secret that I’m a big Latitude fan.
‘I have been to the festival numerous times as a performer and punter, so to be coming back in 2019 as a headliner – five years after my last performance – is a huge treat.
‘I can’t wait to rock up and play the songs for everyone.’
The Shotgun singer will be joined by Primal Scream, Freya Ridings and Sigrid, who will also perform at the event from July 18 to 21.
The festival also boasts a strong comedy lineup, with stand-ups Russell Kane, Jason Manford and Tom Allen Helm all confirmed.
