Luxury fashion retailer Burberry could lose its Royal Warrant if it goes ahead with the planned closure of its Welsh factory.
The company plans to cut 300 jobs when it shuts its site in Treorchy this March.
Bryant said warrants should only go to British companies if they have a “fair employment policy”.
Companies are only entitled to receive Royal Warrants if they have regularly supplied goods or services for a minimum of five consecutive years to the Queen, Duke of Edinburgh or Prince of Wales.
Burberry, which is moving the production of its Treochy site overseas later this year, said it was very much a British company that employed 2,000 people in the UK.
