READ MOREThe 7.3 billion pound ($9.6 billion) deal to buy the UK arm of Walmart, a transaction that could see the combined group leapfrog Tesco as Britain's biggest retailer, is being assessed by the Competition and Markets Authority (CMA).
The CMA said last month it expected to issue provisional findings early next year, ahead of a final report in March.
Sainsbury's chief executive Mike Coupe told reporters he expected the CMA's first report to be published in late January.
Sainsbury's and Asda have both said they believe the CMA will not insist on a level of store disposals that will make the deal, announced in April, unpalatable. ■
