X5 Retail Group has reported sales of RUB126.3bn (£2.63bn) in its first quarter ended March 31, an increase of 8.1% year on year.

The increase in net retail sales was driven by additional store space, price inflation, the positive performance of maturing stores added over the past two years and promotions.

X5 also added 66 stores to its network during the first three months of 2013.
