Britain's competition watchdog said Tuesday it launched a formal inquiry into Google's takeover of cloud data analytics company Looker Data Sciences, as it intensifies scrutiny of technology deals.

The Competition and Markets Authority said it had notified the two companies on Monday that it was opening an initial inquiry and would decide on February 13 whether to escalate it to a more in-depth investigation.

The authority said this month it was looking into whether the 2.6 billion U.S. dollars acquisition would result in less competition in the UK market.

Google said in a statement that "the acquisition of Looker has received regulatory approval in the U.S. and Austria and we continue to make progress with regulators in the UK".

The U.S. tech giant said in June it was buying Looker, which helps customers visualize data, as it seeks to compete with rivals including Amazon in the lucrative cloud service business.

The inquiry comes a week after the authority stepped up pressure on a separate tech deal, by threatening Amazon with an in-depth investigation of its plan to buy a stake in food delivery platform Deliveroo unless it came up with proposals to address competition concerns.

Google has also come under regulatory pressure on various fronts in the U.S., where authorities at both the state and federal level have opened investigations into tech giants.
