A Norfolk and Norwich Festival show has been cancelled because the star is ill.

Portuguese star Mariza, who was due to perform at the Theatre Royal on Sunday evening, has returned to Lisbon to rest after doctors told her to cancel the concert.

World music talent Mayra Andrade, whose music is influenced by the cultures of Portugal, South America and Africa, will take to the stage instead.

People will have the option of receiving a full refund on their tickets. They will be sent a letter by the Theatre Royal explaining the refunds procedure. Theatre goers have been advised not to contact the theatre before they have received a letter.

NNF11 runs until May 21.
