Sue Allen has stepped down as commercial director of Thwaites, the Lancashire brewer and pub operator. Allen, who has been with the company since December 2008 after 18 years at Punch Taverns, is leaving the group as part of senior management changes. These changes will see Steve Magnall join the group from Greene King to take up the role of managing director of its beer arm at the end of this month, while Allen’s old role will not be replaced.
