The SUPERMARKET is facing a probe into fraud about gas pump prices.
The competition watchdog said they were 5p more expensive per liter than expected.
Bosses of major retailers will be formally asked why costs exceed the average margin found in 2019.
The Competition and Markets Authority will also investigate any failure to compete that has caused consumers to pay higher prices for groceries than they should.
But internal documents from one supermarket show it has “significantly increased” its profit target on fuel, spurring similar tactics across the industry.
Some stores are also accused of being slow to provide information after several rounds of evidence gathering.
The CMA investigation has led to numerous calls to deploy the Pumpwatch system to check fuel prices.
FairFuelUK said it was pleased the CMA was “now showing some real teeth and asking for answers”.
