The US pop singer Jimmy Osmond has suffered a stroke and will take time away from the stage, a spokesperson has said.

Osmond completed a performance of Peter Pan at the Birmingham Hippodrome theatre on 27 December before he was driven to hospital and diagnosed with a stroke, the representative said in a statement on the theatre’s website.

Osmond, now 55, was the youngest sibling in the sibling singing troupe the Osmonds and became the youngest person to reach No 1 on Britain’s singles charts with Long-Haired Lover from Liverpool when he was nine.

“He is grateful for all the well wishes and will be taking time out in the new year,” the spokesperson said.

Darren Day, who started rehearsing on Monday, will replace Osmond in the role of Captain Hook in the pantomime from later this week. Osmond’s understudy, Luke Redford, will cover the role in the meantime.

Birmingham Hippodrome’s artistic director and chief executive, Fiona Allan, said; “Everyone here at Birmingham Hippodrome has been deeply saddened to hear of Jimmy’s sudden illness. Jimmy loved being a part of the Hippodrome’s well-renowned panto, and his portrayal of Captain Hook was both dastardly and heartwarming. He won the adoration not just of our audiences, but also of all our staff. We all send Jimmy and his family very best wishes for a speedy recovery.”
