River Island’s pre-tax profit jumped 12.5% last year as it invested in new stores in the UK and overseas.

The fashion retailer recorded a £97.8m pre-tax profit in the year to December 29, while turnover edged up 0.4% to £802.3m.

River Island chief executive Ben Lewis said: “I am pleased with our performance against a tough economic backdrop.

“It reflects the investment we have made in the business and we look forward to further expansion at home and abroad as we build a world class multichannel fashion brand.”

In the year River Island opened 14 new stores - half in the UK and half overseas - refitted eight shops and relocated its London and Liverpool flagships to larger premises.

The retailer also grew its international store estate and now serves 14 countries.

Since year end River Island has invested in its online operations, launching an Australian website in June. It is planning to launch click-and-collect in coming weeks.

Despite the positive performance River Island said the trading outlook “remains cautious”.
