Scottish retail sales experienced a 1.4 per cent drop in June compared with the same period last year, in contrast with the year-on-year rise for the UK as a whole.
Figures released by the Scottish Retail Consortium (SRC) today also indicated a 0.1 per cent rise in food sales in June, the first year-on-year rise in the value of food sales in Scotland since December.
Meanwhile, the value of non-food sales in Scotland last month dropped by 2.6 per cent compared to June 2015.
SRC said that consumer confidence may have been hit by the vote to leave the EU, although it insisted it was not yet possible to properly forecast the impact it had consumers.
Figures released last week by the British Retail Consortium showed the value of UK retail sales for June went 0.2 per cent, although this was a sharp slowdown in the year-on-year rate of growth from 1.4 per cent in May.
