The U.K. Competition and Markets Authority said Nov. 29 that Grafton Group PLC’s planned sale of its traditional trading business in the U.K. to Huws Gray could raise competition concerns and that it will review the deal further unless both parties provide acceptable commitments to resolve their issues, with a deadline of Dec. 6, according to U.K. media reports.

The regulator began reviewing the deal in October and said it made its decision through an expedited process at the request of both companies. On Oct. 1, the CMA had said it was examining whether the deal would lead to a significant reduction in competition within the U.K.
