Albert Manifold has been ousted as chairman of BP due to allegations of 'unacceptable' conduct, which he disputes, claiming he was removed without prior warning or explanation. The BP board expressed disappointment over governance and oversight issues, leading to decisive action. Amanda Blanc, Senior Independent Director, acknowledged Manifold's contributions but emphasized the need for accountability. His removal comes during a turbulent period for BP, which has seen three CEOs and now three chairmen in the last three years. In the wake of this leadership change, Ian Tyler has been appointed as the interim chairman. Following the announcement, BP's shares fell by 10%, prompting a brief trading halt. Manifold, who had no prior experience in the energy sector, joined BP from CRH during a challenging time for the company, which was facing underperformance compared to its peers.
