The UK’s competition regulator has launched a fresh investigation into Facebook over concerns that the tech giant might be abusing a dominant position in digital advertising.

The Competition and Markets Authority (CMA) will look into how the social network gathers and uses certain data and whether it may provide an unfair advantage over rivals in the online classified ads and online dating space.
