Tesco and Sainsbury’s have marginally lost their share of the UK grocery market, according to the latest figures from research analysts TNS Worldpanel.


Tesco and Sainsbury’s grew sales by 5% and 4% respectively during the 12 weeks to 15 June but TNS said the UK grocery sector as a whole grew by 6%.


Morrisons, the UK’s fourth-largest grocer, saw sales rise by 8.1%, while Asda’s sales were up 7.5%, according to TNS.


Edward Garner, director of research at TNS, pointed to “very strong year-on-year growths” at discount retailers Aldi and Lidl, which saw sales rise 21% and 13% respectively.


Tesco, however, still enjoys double the market share of its nearest rival Asda, according to TNS. Tesco accounts for 31.2% of UK grocery sales, TNS said, while Asda’s share stands at 16.8%.

Meanwhile, Garner added that, although some food prices in the UK had “rocketed”, food inflation in the UK was not standing at 20% as had been reported.


“TNS believes that it is more relevant to look at the average household shopping basket, taking account of sales levels and promotions and, as a result, state that price inflation in grocery stood at 4.6% for the 12 weeks ending 20 April,” Garner said.
