Ron Warmington - Chairman


Ron is a Chartered Accountant and a Certified Fraud Examiner and a member of the ACi (Association of Corporate investigators). As Global Head of Banking Investigations at Citibank, directing over 100 investigators dealing with cases in over 100 countries, and as its Head of Security for EMEA, Ron has dealt with every type of fraud and every other form of corporate embarrassment and loss. Under his leadership, Citibank’s fraud-related asset recoveries routinely exceeded USD 100 million p.a. Ron’s team at GE Capital developed a Global Fraud Management Programme that materially increased Corporate profits by slashing fraud-related (and credit-related) losses. Exceptional Returns on Investment were achieved by designing and deploying highly effective / efficient preventive and detective measures. In 2006, Ron flagged up the impending sub-prime / CDO crisis and predicted the Global Financial melt-down. With extensive experience in Internal Audit; Banking; Systems Design; Process Repair and Business Management (including 8 years as CFO of Citibank’s Global Asset Management Business) and a highly successful period as a CFD Trader, Ron has consistently shown that he has the skills, the personality and the drive to deal with the most challenging situations. Between 2012 and 2015, Ron’s company ‘Second Sight’ established the causes of mysterious shortfalls in branches of the Post Office, revealing what has been described as the country’s worst ever miscarriage of justice.
