Yep, King and Murray were named in the claim in their capacity as directors of RRL. The club was also named.
"SDI Retail Services, a company in the Sports Direct group, has been given permission to continue its derivative claim against Rangers Football Club. The claim relates to Rangers' purported termination of its contract with Rangers Retail Limited, a company owned by Rangers and SDI that produces and sells Rangers replica kit and other products featuring Rangers' brands.
SDI's claim, brought on behalf of RRL, seeks to uphold the validity of that contract. SDI is also claiming against David King and Paul Murray, directors of RRL whom (SDI says) were involved in TRFC's decision to purportedly terminate the contract and in so doing acted against the best interests of RRL."
