Tesco-branded milk accidentally sold at Sainsbury’s after supplier mix-up as chain’s bosses launch probe into blunder

SAINSBURY’S supermarket bosses have launched an investigation after one of their stores sold Tesco-branded milk by mistake.

Warehouse and shop staff blunders led to the rival chain’s “Fresher for Longer” being put on their shelves.

“They could not get them off the shelf quickly enough.”

“We’re working with them to understand what happened and apologise for any confusion this may have caused.”

After a similar incident in 2012 in Ely, Cambs, Tesco said: “It’s good to see Sainsbury’s has got great taste in milk.”
