Tesco reported a "strong" performance in its financial third quarter in the UK and Republic of Ireland, unveiling its highest rate of market share growth in the latter in five years.
In the 19 weeks to 6 January the supermarket chain announced a 2.3% rise in like-for-like sales in the UK and Ireland.
During the Christmas trading period, Tesco said it had its “biggest ever” sales week in the UK, driven by the outperformance of fresh food sales - up nearly 4%.
Also during Christmas week, the company handled 58 million customer transactions and 770,000 online grocery deliveries.
Internationally, the company saw like-for-like sales growth of 0.8% across central Europe, but Asia's 9.6% decrease was due to unprofitable selling activities in Thailand and reduced promotional activity, the company said.
