Martine McCutcheon's theatre production company is remaining tight-lipped over whether she is insured to move with “My Fair Lady” to the Theatre Royal in July.

She has recently been plagued with ill health and has missed more than half of the performances of the show, being held at the National Theatre.

Reports in a national newspaper suggested that the show's leading lady must have insurance before the move takes place, to cover box offices losses if her illness persists.
