UK retail sales were up 0.8% on a like-for-like basis from May 2009, thanks to a burst of warmer weather, according to the latest figures from the British Retail Consortium (BRC).

Food sales returned to growth after April's year-on-year decline which stemmed from this year's earlier Easter. The chilly and wet start to the month drove roasting joints, vegetables, comfort foods and sweet treats, such as biscuits and confectionery.

In the sunnier second half of the month, demand turned to salads and fresh fruit, meat and fish, barbecue foods and ice-cream. Beers, wines, soft drinks and juices were popular.

Stephen Robertson, director general of BRC, said: "The sunnier second half of May provided a welcome boost to overall sales. The warmer weather combined with discounts and promotions encouraged spending on clothing, footwear, outdoor DIY and gardening.

"The run-up to the World Cup helped sales of televisions, though this was largely discount-driven. With the tournament getting closer, there should be a further uplift to other football merchandise such as flags and replica kits. After April's dip, food sales growth returned to more normal levels.

"Consumer confidence has clearly improved since last year's lows. But there's still plenty of uncertainty, which is making customers nervous about buying expensive goods, such as furniture, despite widespread reductions. This month's emergency Budget should provide more clarity."
