Several British retailers including TescoTSCO.L, NextNXT.L and PrimarkABF.L have recently cut their profit outlooks. LONDON, Oct 7 (Reuters) - British retailers last month saw their slowest sales growth since shops reopened after COVID-19 lockdowns as consumers reined in spending amid a worsening cost-of-living crunch, a survey from business advisory firm BDO said on Friday. With rising inflation, data suggests that the actual volume of sales is down significantly while it is higher prices that is driving the growth," Sophie Michael, BDO's head of retail and wholesale said.
