May 27 (UPI) -- Ousted BP board Chair Albert Manifold challenges the allegations of his behavior cited for his removal.

In a statement to CNBC, Manifold said he was removed "without warning and without explanation" and that he disputes "entirely the characterization" of his conduct.

The BP board announced his removal Tuesday after just months in the position of chair and director. He was appointed in July to replace outgoing Chair Helge Lund. His interim replacement is BP board member Ian Tyler, a director of Anglo American and former CEO of British construction company Balfour Beatty.

Amanda Blanc, senior independent director at BP, said the board was "surprised and disappointed to learn of governance oversight and conduct issues it deems unacceptable."
