Opera superstar Luciano Pavarotti has had to reschedule two forthcoming UK appearances due to ill health.
Pavarotti recently visited Dubai as part of his farewell tour
The 69-year-old tenor's 11 June concert at the Madejski Stadium in Reading has been moved to 1 July 2006.
His 9 July concert at Chatsworth House, Derbyshire will take place almost a year later, on 8 July 2006.
Pavarotti's spokesperson said he had been forced to move the dates as a consequence of recent neck surgery to repair two vertebrae.
The opera star was admitted to Lenox Hill Hospital in New York on 9 March for the neck operation, described as "routine and regular".
"His doctors reported that he recovered very quickly from his operation and have now advised that the second and final stage of this procedure must take place at the beginning of June 2005," said Terri Robson.
"This situation requires that Pavarotti will, unfortunately, be forced to move two planned UK concert dates during this period."
All tickets already purchased will be valid for the rescheduled dates.
A planned appearance at a tribute concert at London's Guildhall on 7 June is also unlikely, although Pavarotti had not been scheduled to sing at the event.
Organisers for the British Red Cross Royal Gala Ball say they are looking into the possibility of a video link-up.
The legendary performer is currently in Kiev, Ukraine, as part of a farewell tour that has already seen him perform in South Africa, Mexico and the United Arab Emirates.
