(Bloomberg) -- Microsoft Corp. President Brad Smith will meet with UK Chancellor Jeremy Hunt next week to voice his frustration over the shock decision by Britain’s competition regulator to block its $69 billion takeover of Activision Blizzard Inc.

Smith is set to hold talks with Hunt as well as officials from the Competition and Markets Authority, the agency that wielded the April 26 veto, according to people familiar with the discussions, who spoke on condition of anonymity.

Microsoft confirmed that Smith will be in London, where he’s giving a “scheduled talk about the potential of AI and the need for thoughtful regulation of it.” He’ll also hold private discussions on other issues, “including the proposed acquisition of Activision Blizzard as we remain committed to finding creative and constructive ways to address remaining regulatory concerns,” a Microsoft representative said.

Smith is expected to point to the benefits of the acquisition for gamers and push back against the move to block the industry’s largest merger — a decision that will soon play out in a special UK antitrust court. Hunt previously criticized the CMA’s veto, telling a business conference recently that competition watchdogs must “understand their wider responsibilities.”

Despite Hunt’s comments, one of the people said government ministers were “unhappy” with some of Smith’s criticism of the CMA in interviews in which he claimed that the European Union — which approved the takeover — was a better place to do business than the UK. The government holds no formal role in the enforcement of the country’s competition rules, but members of the CMA board are appointed by the UK’s business department.
