Analysts said the group was likely to benefit from soaring viewing figures for the show, which features Scottish singing sensation Susan Boyle.
The company is in its second year of its support for the show. Douglas Jack, of stockbroker Numis, said a 25% year-on-year rise in viewing figures – reaching as many as 13m – should boost trading.
The comments came as Domino’s reported a 9.3% jump in like-for-like sales in the 13 weeks to March 29. Online sales rose by 31.7% to £16.6m as people decided not to dine out.
