“With Becky Hill, Bastille and Myles Smith also on the bill, there’s a real mix of artists for different generations and tastes, and there’s still more to come.
“We put a lot of thought into what happens beyond the main stages, too.
“The food, the entertainment and the spaces where people can spend time together are all part of what makes it a special weekend on the Island.”
Williams is set for a busy 2027 as he will also headline Lytham Festival, the British Grand Prix, and play two massive stadium gigs in Ireland next summer.
