Tony Hayward defends BP's record

The chief executive of BP Tony Hayward has been defending the record of the company in front of a House of Commons committee.

An explosion on a rig off Louisiana in April killed 11 workers and triggered the worst oil spill in US history.

Since then the leaking oil well has been capped, Mr Hayward's departure has been announced and BP has published its own detailed account of what went wrong.

My Hayward told MPs that the "Gulf of Mexico is a more challenging drilling environment than many other parts of the world".
