Grocery retailer Ahold has extended its cost-savings programme from E350m (£283.9m) to E600m (£486.8m).

Ahold said it will include sourcing and promotional costs to invest in creating a better offer and value for customers.

Next year, the grocer plans to convert many of its 82 Dutch C1000/Jumbo Supermarkten stores to Albert Heijn. It also intends to double the  number of Albert Heijn stores in Belgium.

Further investment in its online offer and home delivery service is also planned.
