Google may have to make changes in the UK so people have more choice over which search engine they use, following a landmark decision from the regulator. The Competition and Markets Authority (CMA) has designated Google with "strategic market status" under a law which came into force in January. The decision does not mean the regulator has found wrongdoing at this stage. Instead, it opens the door to what it called "proportionate, targeted interventions" to ensure the market is competitive.
