Supermarket petrol station merger could increase prices for motorists and shoppers

Competition and Markets Authority opened a Phase 1 investigation into Asda's acquisition of Arthur Foodstores Limited.

CMA found that the deal raises competition concerns in 13 locations across the UK, in each of which the merging businesses currently compete for customers.

The deal could therefore lead to consumers and businesses in these areas facing higher prices or lower quality services when shopping or buying fuel.
