Gulf oil spill commission criticises White House

A commission investigating the response to the BP oil spill in the Gulf of Mexico has strongly criticised the White House in a number of areas.

The Obama administration blocked government scientists' efforts to inform the public of worst case scenarios, a draft report said.

Officials were said to have been too optimistic about handling the disaster, one of the worst in US history.

The White House disputes this, saying officials "were clear with the public".

The BBC's Washington correspondent Steve Kingstone reports.
