British shoppers set aside their concerns about fast-rising inflation following the Brexit vote and stepped up spending last month at the fastest rate in years, encouraged by fine weather, official data showed.
Retail sales volumes jumped by 2.3 per cent in the month of April, as reported by the Office for National Statistics(ONS) on Thursday.
The robust data contrasts with a generally downbeat tone so far this year, as a pick-up in inflation triggered by the fall in the pound after last year's Brexit vote ate into households' disposable income.
The rebound followed a sharp 1.4 per cent fall in March that capped the weakest calendar quarter since 2010.
Looking at the value of retail spending - which adds in the extra amount shoppers spend because of higher inflation - sales in the three months to April were up 6.2 per cent on a year earlier, the biggest rise in 15 years.
Sterling rose almost half a cent against the US dollar after the data, rising above $1.30 for the first time in almost eight months, and British government bond yields fell to a one-month low.
