The Competition and Markets Authority in the UK has just issued a notice of extension in its investigation of Microsoft’s proposed acquisition of Activision Blizzard. The CMA was due to accept final undertakings or make a final order by July 18th, but thanks to fresh negotiations with Microsoft it has now extended that by six weeks to August 29th. “However, the Inquiry Group aims to discharge its duty as soon as possible and in advance of this date,” says CMA group chair Martin Coleman.
