London, England (CNN) -- Outgoing BP Chief Executive Tony Hayward was due to appear Wednesday before a British parliamentary committee investigating the implications of the Gulf oil disaster on deepwater drilling.
The Energy and Climate Change Committee is looking at the government's moratorium on deepwater drilling in Britain and whether existing safety and environmental standards need updating in light of the massive spill in the Gulf of Mexico.
Hayward came under fire for his handling of the spill, one of the worst in U.S. history.
He wil step down as chief executive, effective October 1.
