PROTESTERS blocked the entrance to the Competition and Markets Authority (CMA) yesterday, accusing the watchdog of whitewashing energy companies’ overcharging of customers to the tune of £1.7 billion.

The CMA called its probe “the most comprehensive investigation into the energy market since privatisation” but initial findings on Britain’s Big Six energy companies “ripping off” customers were not included in the final document.

Switched On London activists scaled the walls of the CMA HQ yesterday to unfurl a banner reading: “CMA <3 Big Six. Public energy now.”
