A WIDELY expected investigation of Amazon’s attempt to buy a significant stake in Deliveroo was launched by Britain’s competition watchdog yesterday.

The Competition and Markets Authority (CMA) announced that it has began an inquiry into the transnational online retailer’s £450 million offer to the food-delivery company.

The CMA said that Amazon and Deliveroo had failed to address its concerns that the investment could be bad for market competition and have a negative effect on customers, restaurants and grocers.
