Sir Paul McCartney has had to cancel his Japanese tour due to poor health.

The Beatles legend already postponed two dates in Tokyo over the weekend on doctor's orders, with the star now having to take "complete rest" for a suspected virus.

McCartney said in a statement: "Thank you so much for your kind messages of support. I'm so very touched.

"Unfortunately my condition has not improved overnight. I was really hoping that I'd be feeling better today. I'm so disappointed and sorry to be letting my fans down."

Organiser Kyodo Tokyo added: "(McCartney) will regrettably have to cancel the remaining Japanese shows. Paul is still not feeling better and this cancellation is unavoidable."

The 71-year old singer is still due to perform in Seoul, South Korea on May 28, followed by 19 shows across the US.
