The chief executive of one of England’s largest NHS integrated care boards has been suspended while an internal whistleblowing investigation gets under way. Mark Fisher, who heads the Greater Manchester Integrated Care Board (ICB), has been asked to step aside on a temporary basis as the organisation examines concerns raised through its whistleblowing process.
A spokeswoman for the ICB confirmed that Fisher’s suspension is “precautionary,” stressing that the investigation has not reached any conclusions and that it is important “no assumptions are drawn” while the process moves forward. The ICB oversees commissioning and funding of health services for the Greater Manchester region, making it one of the most influential health bodies in the country.
To maintain operational stability, deputy chief executive Colin Scales has taken over Fisher’s responsibilities during the investigation. A spokesman said the leadership shift is intended to “ensure continuity and stability” across all services while the inquiry is conducted. Due to confidentiality rules and the need to protect all parties involved, the ICB has declined to provide further details at this stage.
Fisher has led the integrated care board since its formation in 2022, playing a key role in Greater Manchester’s ongoing NHS reforms following the 2022 restructuring that introduced ICBs across England. Earlier this year, he announced plans to retire in 2026 after a 42-year public service career that included senior positions such as director general at the Cabinet Office and secretary to the Grenfell Tower Public Inquiry.
The suspension comes at a sensitive moment for the NHS, as ICBs across the UK face growing scrutiny over governance, financial pressures, and workforce shortages. Several ICBs have been under review this year due to performance concerns, and Greater Manchester has been navigating major challenges, including post-pandemic demand and ongoing industrial action across the health sector. The outcome of the investigation into Fisher’s conduct will be closely watched given the strategic importance of the region’s health board.
