Discounters have increased their share of UK grocery from 5.7% in 2002 to 6.3% in 2005, according to new figures from IGD.

However, their share in the UK remains well below the average for across Europe, where discounters now account for 18% of the Continent's grocery market - and IGD forecasts that their march across the Continent will slow.

The data is contained in an IGD report, Winning in a Discounter's World. "The sector experienced phenomenal growth in Europe after the introduction of the euro in 2002, and related consumer concerns about rising prices in the eurozone," said Ben Miller, international programme manager at IGD. "But we now expect growth to slow to pre-2002 levels."

Discounters have the greatest market share in Norway, controlling almost half of grocery sales.
