Britain's competition regulator on Friday said Photoshop owner Adobe Inc's $20 billion buyout of cloud-based designer platform Figma could reduce innovation.

The Competition and Markets Authority (CMA) said the deal would be referred to a phase 2 investigation "unless the parties offer acceptable undertakings to address these competition concerns."

Adobe and Figma did not immediately respond to Reuters' request for comment.
