The CEOs of Sainsbury’s, the UK’s second largest supermarket, and Asda, the third largest, will be questioned by a British parliamentary committee ahead of the proposed merger of the two companies.
Sainsbury's announced a $9.77 B deal to buy U.S. group Walmart's Asda in April. If it goes ahead, the combined giant will overtake Tesco as Britain's biggest supermarket group.
The competition regulator has started a preliminary probe into the deal ahead of a formal investigation, while on Wednesday lawmakers from the Environment, Food and Rural Affairs Committee said that they would also gather evidence.
"Grocery retailers do not have a great record of treating their suppliers well," the committee's chair Neil Parish said in a statement.
"My committee is holding this session to investigate how the biggest potential shakeup of the grocery market in recent years could affect British farmers and suppliers, as well as consumers."
Sainsbury's Mike Coupe and Asda's Roger Burnley will be grilled on June 20.
