UK blocks Microsoft's acquisition of Activision Blizzard.

Microsoft's president, Brad Smith, criticized the UK regulator's decision to block its acquisition of Activision Blizzard, saying it had shaken confidence in Britain as a destination for tech businesses. The Competition and Markets Authority (CMA) blocked the deal, saying it could hit competition in the nascent cloud gaming market. Microsoft hit back, saying it was "probably the darkest day in our four decades in Britain" and sent the wrong message to the global tech industry about the UK. The company said it would appeal the decision.
