On 13 November 2020, the Competition Appeal Tribunal (CAT) partially upheld JD Sports’ appeal against the CMA’s decision to prohibit its completed acquisition of Footasylum requiring it to fully divest Footasylum.[1] The CMA found that the parties were close competitors in sports-inspired casual clothing and footwear in stores and online.
