Young's claims its Admiral's Pie is the UK's best-selling frozen ready meal. Seven other products will also be affected by the packaging change.
Matt Whelan, marketing manager for Young's, said: ‘We had to do significant in-store testing to ensure that the visibly smaller pack was properly communicated and did not negatively affect consumer perceptions of the product.'
