Prior to his Director role, Mark acted as Interim Chief Executive of the LSB and has had a nearly forty-year career of public service. From 2010, he led the Financial Services Compensation Scheme for nine years, transforming its capability in the wake of the financial crisis so that it is able to protect consumers in the event of major failures and putting many of its services on-line. Before FSCS, Mark was a civil servant in both policy and delivery roles. This culminated in Director-General roles in both Home Office where he was responsible for counter-terrorism, organised crime and International work from 2002 to 2005 and in HM Treasury where he was the Managing Director for Budget, Tax and Welfare between 2005 and 2010. Mark has also worked as a civil servant on education, employment and welfare issues.
