UK supermarket chain Asda has reported a 6% rise in full-year same-store sales, and announced it is opening a new Bangladesh sourcing office for its George clothing line in April.

The retailer said in a trading update today that sales were also up 4.6% for the fourth quarter.

Growth was driven primarily by higher numbers of customers and higher average spend.

Speaking about the Bangladesh opening, Asda CEO Andy Bond said: "Having a dedicated team on the ground in Bangladesh means we can conduct unannounced factory audits more easily; we can help sort technical or quality issues more quickly, and we can improve worker standards in the factories that supply us by getting even closer to them."

He said the final few weeks of the fourth quarter were impacted by some of the most challenging weather conditions Asda has ever experienced, referring to ongoing snow and ice.

Bond noted that George had regained the top spot for clothing volume in the UK ahead of M&S, Primark and Debenhams during the period.

He said that consumers were demanding less waste, clear ethical standards, and higher quality garments.

Geroge's men's 'Moob Tube' and 'Tummy Tamer' dress launches were both heralded as successes of the period.

The company is also launching a new wedding collection from May, able to kit out an entire wedding party for under GBP200 (US$311).

Asda's US parent Wal-Mart this morning (18 February) reported a 7% increase in full-year earnings.
