Retail Week looks ahead to the next seven days, with the latest grocery market share data from Kantar and Nielsen on the agenda.

Kantar Worldpanel and Nielsen both unveil their latest market share data for the grocery sector on Tuesday August 22.

Britain’s supermarket chains will be hoping to build momentum after hot weather and major sporting events – including Wimbledon, the British Grand Prix and the British and Irish Lions tour – boosted sales in July.

According to Nielsen, total grocery sales were up 5.1% year-on-year in the four weeks to July 15.

All of the UK’s major grocers enjoyed rising sales during that period for the first time since July 2013, Nielsen data suggested.

Rival figures from Kantar painted a similarly pretty picture for the sector, which is being aided by food price inflation falling after the Brexit vote, and the subsequent fall in the value of the pound.

Kantar said Lidl was the fastest growing supermarket, increasing sales 19.4% – its quickest rate of growth since October 2014.

That helped it grow its market share to 5.1%, pulling it level with upmarket rival Waitrose as Britain’s joint-seventh biggest grocer.
