Factbox: Developments in the Gulf of Mexico oil spill

(Reuters) - Here are some developments in BP Plc's Gulf of Mexico oil spill, the largest in U.S. history.

TOP DEVELOPMENTS

* The Obama administration scrambled on Friday to respond to a court's refusal to reinstate a ban on deepwater drilling imposed after the massive BP oil spill, while insisting the ruling was not a major setback for the policy.

* The U.S. Court of Appeals for the Fifth Circuit ruled 2-1 against the administration's request to stay a lower court decision lifting the six-month drilling ban, saying the government failed to show how it would be irreparably harmed if a stay were not granted.

CAPTURE/CONTAINMENT/CLEANUP

* BP said on Friday it is hooking up a third vessel to increase oil-capture capacity at the Gulf of Mexico spill to 53,000 barrels a day from 28,000 barrels a day.

* BP could remove the current containment cap and one siphoning system on Saturday to prepare to install a new cap and seal designed to capture more crude oil, the top official overseeing the spill response said on Friday.

* BP said on Friday that its oil-capture systems at the leak collected or burned off 24,395 barrels of oil on Thursday.

* Drilling on a BP relief well reached 12,780 feet beneath the seabed, or 220 feet from the bottom of BP's blown-out Macondo well, spokesman Mark Proegler said on Thursday.

MARKET IMPACT/COMPANIES

* Singapore state investor Temasek, whose energy and resources portfolio grew by $3.6 billion last year, on Thursday dismissed talk it had held discussions with BP for a strategic stake.

* BP shares traded in New York were down by 2 percent on Friday trading at about $33.15. Shares traded in London have rallied 20 percent from their June 29 low to trade at about 363 pence.

* BP shares had lost around half of their value since the spill started after an oil rig exploded in the Gulf in late April, killing 11 men.

POLITICS/POLICY

* Suspected targets in the criminal investigation into the Gulf Coast oil spill may cover more than BP, U.S. Attorney General Eric Holder said on Thursday.

* The White House is sending BP Plc a list of questions about its efforts to cap a gushing oil well in the Gulf of Mexico and is ordering the company to respond within 24 hours, a U.S. official said on Thursday.

* Florida Governor Charlie Crist on Thursday called for a special state legislature session to consider a constitutional amendment to strengthen the ban on oil drilling off Florida's coast.
