The UK's Competition and Markets Authority (CMA) has given itself a bit more time to finish its investigation into Microsoft's proposed acquisition of Activision Blizzard.

In a letter, the organisation announced it had extended the deadline for publishing its findings from March 1st of this year to April 26th. This is due to the sheer "scope and complexity" of the case, as well as "the need to consider a large volume of evidence as well as main party and third party submissions," according to inquiry group chair Martin Coleman.

12 months ago, Microsoft announced it was buying Activision Blizzard for a record-breaking $68.7 billion. Since then, competition bodies around the world have been looking into the deal. Some, such as Brazil and Saudi Arabia, have given the acquisition the thumbs up, but the EU, UK and USA are looking further into the impact the deal would have on the market. Like in the UK, the EU competition regulator is conducting a deeper investigation into the acquisition. 

The US' FTC is suing to block the acquisition, with no "substantive" settlement discussions taking place with Microsoft at the moment.

There have been reports that Microsoft is planning 'sweeteners' for the EU to ensure that the Activision deal goes through.
