Heard the 8th June date has been cancelled and the 5 Days that have been announced are the final Festival Headliners:
Fri 6th - Massive Attack
Sat 7th - Jamie XX
Fri 13th - Turnstile
Sat 14th - Charlie XCX
Sun 15th - London Grammar
Other than your personal dislike of them and the fact they divide opinion (neither of which are valid reasons), by what metric are they not 'worthy' of a headline slot? Because pretty much every subjective metric proves they are.
