German discounter Aldi has launched a price-cutting campaign in a bid to poach customers from Tesco and Asda.

Joining the much-publicised price wars between the UK's big two, it has slashed prices across 130 lines - 15% of its core grocery range. The cuts have been backed by a series of print adverts in tabloid newspapers.

"Aldi is supporting the customer during difficult times of inflation rises and subsequent mortgage hikes," said Tony Baines, UK MD of buying.

TNS Worldpanel figures show Aldi registered double-digit growth in the 12 weeks to 16 July, with sales up 11%. It also achieved an increase in market share of 0.1 percentage points to 2.6%, lending support to claims by analysts that the tightening of public purse strings would lead to a boom for hard discounters.

The retailer is also running TV ads this month promoting its Siana anti-wrinkle night and day creams, starting tomorrow.
