The bassist of the Arctic Monkeys has quit the band permanently.

Andy Nicholson initially sat out the band's North American tour due to fatigue, but the band have now confirmed the absence is for good.

“We are sad to tell everyone that Andy is no longer with the band,” said a statement posted on their official website.

“We have been mates with Andy for a long time and have been through some amazing things together that no-one can take away. We all wish Andy the very best.”

Nick O’Malley, Nicholson's stand-in, will remain with the band for the rest of the summer.
