Rocio Concha, Which? Director of Policy and Advocacy, said: "Amazon is the go-to online retailer and marketplace for millions of people. However, if it is abusing a dominant position then consumers may be having less choice or paying higher prices, so it's right that the CMA is investigating these concerns and is prepared to take action if required. "This is the latest in a growing number of investigations into concerns that tech giants may be limiting competition and harming consumers. While welcome, these cases can be slow and UK consumers would be better served by the government giving powers to the Digital Markets Unit so it can introduce and enforce a pro-competition regime for digital markets." -ENDS-
