Britain’s competition watchdog said on Friday it was planning to review if JD Sports Fashion Plc’s acquisition of smaller rival Footasylum “substantially” reduced competition in the sector.

The Competition and Markets Authority served an initial enforcement order in relation to the deal, which was announced in March and valued Footasylum at up to 90 million pounds ($119.6 million).

Initial enforcement orders are put in place to prevent businesses from integrating after a possible merger while the watchdog decides if it needs to launch an investigation.
