An assessment of the $40 billion acquisition contains worrying implications for national security and the U.K. is currently inclined to reject the takeover, Bloomberg reported, citing a person familiar with government discussions.
Oliver Dowden, the U.K.'s secretary of state for digital, culture, media and sport, said in April that regulators were intervening in the semiconductor company's proposed acquisition of Arm from Softbank Group SFTBY.
Dowden asked the Competition and Markets Authority to prepare a report on whether the deal could be deemed anti-competitive, along with a summary of any national security concerns raised by third parties.
The report was delivered last month.

Dowden is set to decide on whether the merger needs further examination by the U.K.’s competition authorities.
