Adele has been forced to cancel all of her remaining gigs and public appearances for the rest of the year, as she undergoes throat surgery.

It's another setback for the singer who has struggled to overcome vocal problems since pulling out of a tour in June.

Rescheduled UK shows for November have now been permanently called off.

A statement from her record company said she's expected to make a "full recovery".

'Disappointment'

Fans with tickets for those concerts in Wolverhampton, Blackpool, Bournemouth, Cardiff and Plymouth will now be offered a full refund.

Adele's record label XL Recordings apologised for the "inconvenience" and "disappointment" of pulling the shows.

A statement continued: "Doctors have ordered her to rest her voice and completely recuperate before looking to schedule any work commitments."

Adele, whose second album 21 is the biggest selling of the year so far in the UK and US, has struggled with illness since the summer.

In July the singer told Radio 1 she had the "all-clear" from a problem which saw her cancel a US tour in June.

"It's basically a hole in your vocal cord," she said at the time. "But I sang through it so that's why it popped. I'm better now it's fine."

In September the beginning of her UK tour was delayed as she announced she was suffering from a "severe chest infection".

Then earlier this month she pulled out of a US tour, once again suffering from vocal problems.

In a blog post on her website she wrote: "I have never been able to fully recover from any of the problems that I've had and then continue to rest even once I'm recovered, because of my touring commitments.

"I've been offered the chance to not tour at all to save anything like this from happening again, but I simply hate letting you down."
