Why does Microsoft need British consent to acquire Blizzard?

Because Microsoft's acquisition of Blizzard involves cross-border transactions, it needs to be approved by the British government.

As an American company, Microsoft's acquisition of a multinational company like Blizzard involves transnational investment and mergers and acquisitions, which may have a significant impact on the British market. According to British laws and regulations of regulatory agencies, any cross-border transactions involving foreign investors need to be reviewed and approved by the government. This is to ensure that the transaction will not have a negative impact on British national security, economic interests or the competitive environment. Therefore, Microsoft's acquisition of Blizzard needs the consent of the British government to ensure that the transaction complies with relevant laws and policies and protects the interests of the UK.
