Downing Street responds to stinging attack from US firm’s president over blocking of $69bn Activision deal

Downing Street has defended the UK as an “extremely attractive” place for tech startups after Microsoft’s president said Brexit Britain was worse for business than the EU, in a stinging attack on the UK’s decision to block a $69bn (£55bn) deal to take over Activision Blizzard.

Microsoft rounded on the Competition and Markets Authority (CMA) on Thursday after a surprise decision to block its planned takeover of the Call of Duty games developer, with its president, Brad Smith, describing it as the “darkest day in our four decades in Britain”.
