British shop prices declined at the slowest rate since August last year, according to an industry survey published on Wednesday, adding to tentative signs that price pressures may be building since June's Brexit vote. 
The British Retail Consortium said shop prices were 1.6 % lower in July than a year ago, shallower than June's decline of 2.0%. 
Some business surveys suggest that sterling's sharp depreciation since the June 23 vote to leave the European Union has pushed up the price of imported goods, many of which will end up in shops. 
British inflation has been below the Bank of England's 2 % target for two-and-a-half years and last year it was zero, the lowest since comparable records began in 1950. 
But consumer prices have started to edge higher again, rising 0.5 % in the year to June.
