Scottish sales fell by 1.1% in June 2014, compared with June 2013, when they had increased by 2.8%, according to the report released by Scottish Retail Consortium (SRC) and KPMG.

Like-for-like sales in June fell by 2.6% on last June, when they had increased by 0.3%.

Taking account of shop price deflation, total June’s total sales grew 0.7% in real terms, the highest real term growth this year, excluding January and Easter, the agency said.

During the period, total food sales were 1.4% down on June 2013, when they had increased 4%, while non-food sales decreased by 0.8% on a year earlier when they had increased 1.8%.

Fashion, clothing and footwear categories were the best performing category in June.

According to the report, total Scottish sales growth was below the UK in June.

Scottish Retail Consortium Policy and External Affairs head David Martin said: "Despite June’s retail figures showing a slight improvement on the previous month they rounded off a disappointingly weak second quarter.

"Warmer weather at the start of the month helped to get shoppers out, but as the weather cooled down so did sales.

"The continued decline in like-for-like food sales in June is suggestive that last month wasn’t any different.

"Despite a slight set back in consumer confidence in June, overall consumer confidence has rebounded significantly throughout 2014 and where consumers have made savings, they now have the confidence to loosen their belts and increase spending on those discretionary non-food items," Martin added.

KPMG Retail head David McCorquodale said: "What the consumer is saving in the battle of the grocers is not necessarily being recycled into the non-food categories.

"In non-food, it is encouraging to see the fashion and footwear category performing well and with less discounting than recent years. However, the uplift in household and furniture sales seen earlier in the year has regressed with confidence levels receding again, perhaps caused by wage rate inflation not rising in real terms as hoped or through fears around a rise in interest rates," McCorquodale added.
