THG said Allen had been brought in as non-executive chair with “a clear mandate to refresh” the retailer’s board and to further strengthen governance and diversity. 

Allen will also work with THG founder and chief executive Matthew Moulding “in developing the management team, as well as refining the Group’s strategy.”

His appointment comes as Moulding looks to reassure investors following a rocky couple of months and concerns about the direction of the retailer. THG said that Allen’s appointment will allow for Moulding to focus on his role as chief executive.
