A reminder of the timeline of events in the Gulf of Mexico oil spill:
- 20 April 2010: Explosion and fire on Deepwater Horizon rig kills 11 workers and injures 17. The rig is owned by Transocean Ltd and licensed to BP.
- 22 April: Rig capsizes and sinks, leading oil to discharge through the gulf.
- 30 April: Then BP boss Tony Hayward says company accepts responsibility for the spill and promises to compensate all those affected.
- 22 June: After receiving criticism for his handling of the crisis - including comment he would like his life back - Hayward hands day-to-day reponsibility for spill operations to Managing Director BOB Dudley - later named as next CEO.
- 29 September - BP permanently seals the leaking well.
BP claims 3.26 million barrels leaked from the well in total, while the US government puts the spillage at around 4.9 million barrels.
