UK chocolatier Thorntons booked a leap in full-year earnings as a revamp of its stores bore fruit.

The company saw pre-tax profits rise 37% to GBP7.1m (US$14.4m) during the year to 30 June.

Revenue rose 5.3% to GBP186m thanks to a slew of new products.

Chairman John von Spreckelsen said the last 12 months had been a "significant year" for Thorntons.

"Having stopped the decline in sales during the first quarter, our efforts for the remainder of the year focused on delivering consistent sales growth across all channels," von Spreckelsen said.

"While we are encouraged by our success, we believe that there is further substantial progress to be made."
