Aldi overtakes popular Co-op supermarket to become UK's fifth largest grocer
Discounter Aldi has overtaken the Co-operative to become Britain's fifth largest grocer, according to new figures.
Aldi's sales rose 12.4pc year-on-year in the 12 weeks to January 29, taking its market share to 6.2pc, ahead of the Co-op's 6pc, data from Kantar Worldpanel shows.
The past quarter saw Aldi attract 826,000 more shoppers than during the same period last year, underpinned by an extensive programme of store openings.
Supermarket sales overall were up 1.7pc on last year, with eight of the nine major retailers seeing growth over the quarter.
Kantar said supply issues affecting fresh produce over the last few weeks had affected sales.
Morrisons was the fastest-growing retailer within the big four, increasing its market share for the first time since June 2015 with a sales increase of 1.9pc year on year, helped mainly by customer demand for its premium own label range.
Tesco grew for the fifth period in a row - albeit at a slower rate than previously - with sales up 0.3pc, resulting in a market share drop to 28.1pc.
Sainsbury's sales remained flat, while Asda suffered a 1.9pc fall but managed to increase the number of shoppers visiting its stores compared to the same period last year.
Elsewhere, Waitrose, Lidl and Iceland all continued to inrease sales by 3.4pc, 9.4pc and 8.6pc respectively.
Meanwhile, rising prices - which consumers saw at Christmas for the first time since 2014 - have continued into 2017, with like-for-like inflation on a basket of everyday groceries climbing to 0.7pc.
Kantar said the increase would mean shoppers would find themselves around £27 worse off if prices continue to rise at the same rate for the rest of 2017.
Fraser McKevitt, head of retail and consumer insight at Kantar Worldpanel, said: "Just a decade ago Aldi was the UK's tenth largest food retailer, accounting for less than 2% of the grocery market.
"Since then the grocer has grown rapidly, climbing the rankings by an impressive five places to hold a 6.2pc market share."
Aldi UK and Ireland chief executive Matthew Barnes said: "Aldi customers get products of comparable quality to the leading brands at prices that are significantly cheaper than any of our competitors.
"This unique offering is resonating with British shoppers and we are opening 70 new stores this year to help keep up with customer demand."
Co-op retail chief executive Steve Murrells said: "Our strategy is delivering strong results as we continue to focus on our core convenience business, with the right stores in the right location with the right range.
"According to Kantar, we are the most frequently visited retailer in the UK. Our offer and revised ranging meets the 'little and often' mantra of the modern-day shopper and is tailored to meet the needs of local communities, whether it be top-up shopping or food on the go."
Market share figures from rival analysts Nielsen also has Aldi in fifth place at 7.2pc, significantly ahead of the Co-op at 4.7pc and Waitrose with 4.5pc, having moved ahead of them both in late 2014.
Nielsen's UK head of retailer and business insight, Mike Watkins, said: "We anticipate the industry to grow around 2pc this year, an improvement on 2016, primarily due to the return of cost price inflation after three years of deflation and the depreciation of sterling - yet grocery spend remaining robust despite price rises.
"The discounters will continue to grow faster than this due to the acceleration of new store openings which could push their market share to 13pc for the first time ever."
