The UK division of Domino's Pizza yesterday upped the stakes in the battle for the home delivery pizza market by claiming market leadership. Domino's Pizza, which holds the British franchise for the US brand, reported a 33% rise in interim sales to £46.4m (US$66.3m) and turnover worth £20.8m (last year: £14.5m) for the six months to 1 July. This generated pre-tax profits of £1.18m (£1.02m). However, these figures include sales in Ireland and all sales through franchisees.
