James Purnell, the former chief executive of City advisory firm Flint Global, has been urged by Liberal Democrats to be excluded from decisions concerning the future of Thames Water should Andy Burnham become prime minister. Purnell resigned from Flint Global on Wednesday and is anticipated to join Burnham’s team. Flint Global counts clients within the water industry, including investors related to Thames Water.

The call for Purnell’s recusal comes amid ongoing government deliberations over Thames Water’s financial crisis. The utility, which supplies water to approximately 15 million people, is saddled with debts estimated at £15 billion. The government is currently considering placing Thames Water under a special administration regime—a form of temporary public ownership—after rejecting a £10 billion private-sector rescue proposal backed by the company’s shareholders and creditors.

Flint Global’s website highlights its advisory role for regulated water companies and major institutional investors. Reports indicate that the firm provided counsel to a group of Thames Water bondholders during efforts to negotiate a rescue deal. This has raised concerns about potential conflicts of interest should Purnell become involved in decisions affecting the company.

Tim Farron, the Liberal Democrat environment spokesperson, criticized Burnham’s appointment, noting Purnell’s recent role lobbying for Thames Water, which has faced significant scrutiny over its environmental record, including sewage discharge incidents and fines for pollution violations. Farron emphasized that Purnell should be fully recused from any involvement in matters related to Thames Water and broader water policy decisions.

The government’s approach to resolving Thames Water’s predicament remains closely watched, given the company’s essential service role and the potential implications of its financial restructuring for customers, investors, and environmental standards. Burnham’s potential premiership and his staffing choices are now under increased scrutiny as stakeholders seek assurance of impartiality and transparency in managing this high-profile case.
