BP delays key test on Gulf of Mexico oil well

BP has delayed a key test on a newly-installed well cap aimed at stopping the flow of oil in the Gulf of Mexico.

BP and US Coast Guard officials said further analysis was needed before pressure testing could begin.

If it proves successful the well will be kept "shut in" and the leak halted until relief wells plug it entirely.

The BBC's Andy Gallacher explained BP's new plan to Evan Davies.
