BP’s board of directors unanimously voted to remove Albert Manifold as chairman on May 26, following multiple whistleblower complaints alleging aggressive conduct and improper handling of sensitive information. He lasted less than eight months in the role.

The decision sent BP shares tumbling as much as 10%, a sharp reaction that signals investors were caught off guard by the severity of the situation.

What happened inside BP

Manifold joined BP as chairman on October 1, 2025, arriving with a strong reputation built during a decade running CRH plc, the building materials giant, from 2014 to 2024. His mandate was clear: accelerate BP’s return to its traditional oil and gas roots after a period of transition toward cleaner energy.

His background in cost discipline and capital allocation made him, on paper, a natural fit for that job. BP needed someone who could refocus spending, streamline operations, and convince the market that the company’s best days were still tied to hydrocarbons.

Instead, whistleblower allegations began surfacing that painted a very different picture of his leadership style. The complaints described a pattern of aggressive behavior, essentially bullying, along with accusations that Manifold mishandled sensitive information.

Manifold, for his part, disputes the board’s characterization of events and has indicated he intends to challenge the decision.

Why governance matters more than ever in energy

The whistleblower angle adds another layer. When whistleblower complaints actually lead to the removal of a chairman at a company the size of BP, it sends a signal to every other major corporation: these mechanisms have teeth.

What this means for investors

The 10% share price drop is the market pricing in uncertainty. Who replaces Manifold? Will the new chairman continue the pivot back to oil and gas? How much management bandwidth gets consumed by the fallout?

For longer-term investors, the more important question is what this reveals about BP’s internal culture. A chairman accused of bullying who gets removed in under a year raises fair questions about the vetting process that put him there in the first place.

The succession choice will be the clearest signal of where BP heads next. If the board selects another operations-focused leader with fossil fuel credentials, the strategic pivot continues. If they opt for someone with a more balanced energy transition background, the Manifold era may end up being a brief, contentious footnote in BP’s long and complicated history.
