Oil giant BP has removed its chairman Albert Manifold over "serious concerns" related to "important governance standards, oversight, and conduct".

Senior independent director Amanda Blanc said the board had been "surprised and disappointed to learn of governance oversight and conduct issues it deems unacceptable and has taken decisive action".

Manifold had been in the position less than a year. Shares tumbled by 6% following the news of his removal.

Ian Tyler has been appointed interim chair with immediate effect.

Manifold joined BP in September 2025 as a non-executive director and was appointed chair the following month.

At the time of his appointment, BP said Manifold had "a strong track record of strategic leadership and operational delivery".

His removal comes after BP reported a doubling in profit following a surge in oil prices since the beginning of the Iran war.

In its first results since the conflict broke out, the energy giant reported profits of $3.2bn (£2.4bn) between January and March after an "exceptional" performance in its oil trading business.

The company said it would begin the search for a permanent chair.

Interim chair Tyler said the board had "deep conviction" in the strategic direction the company had laid out.

It had been "very impressed" with chief executive Meg O'Neill since she took over last December, he added.

"She has already taken bold action to simplify and strengthen the organisation such as announcing the move to a clearly defined upstream/downstream model."

The change reflects increasing supply concerns over certain fuels due to the effective blockade of the Strait of Hormuz.
