Domino's Pizza has posted falling annual profits and admitted store openings will be hit this year amid an escalating row with its franchisees. The pizza delivery company said that, while its pipeline of new stores is set to hold firm in 2019, the actual number of openings is likely to be lower given 'ongoing franchisee discussions'. The news came as it posted a 22 per cent plunge in annual profits to £61.9million after suffering 'growing pains' in its international business. Domino's is working to resolve a dispute with disgruntled store operators, who have set up a group called Domino's Franchise Association UK & Ireland, demanding more support from the company in the face of rising costs. Chairman Stephen Hemsley said the company was 'determined to improve operational and financial performance in our international businesses, and ensure a smoother relationship with some of our franchisees'.
