Irish rockers U2 have sensationally ended their 27-year relationship with Island Records in advance of their upcoming Greatest Hits Collection.
Media reports hint the move to Mercury may be prompted by its new president, Jason Iley, whose team looked after the stars at Island before he quit in May.
U2 ended their US contract with Island for similar reasons 10 years ago. They switched to Interscope in pursuit of new boss Jimmy Iovine after he jumped labels.
The band has so far refused to comment on the management change.
The Greatest Hits Collection is due for release next month.
