Schwarz Group-owned discounter Lidl has advertised in high-profile local newspapers stressing a commitment to Greek suppliers.

The retailer is responding to negative publicity resulting from politicians and official investigators accusing the German retailer of charging higher prices for products in crisis-struck Greece than it does in other European markets.

In the ads, Lidl says it supports the Greek manufacturing industry by distributing Greek products worth more than E600m (ÂŁ481m), both locally and abroad.
