FACTBOX - Major nationalisations and bailouts

(Reuters) - Mortgage lender Bradford & Bingley is being nationalised and part of its business is to be sold to Spanish bank Santander.

Following is a list of some previous nationalisations or bailouts by the government:

* ROLLS-ROYCE - In 1971 Rolls-Royce was rescued from bankruptcy following mounting engine development costs. The deal split the car business from aeroengines which was nationalised.

* BRITISH LEYLAND - In 1968 a merger created the vast carmaker with 70 factories. The group ran out of cash in April 2005 and cut 5,000 jobs after failing to secure a rescue deal with China's Shanghai Automotive Industry Corp. The company was later sold to Nanjing Automobile Group for an unknown sum.

* JOHNSON MATTHEY BANK, NATIONAL HOME LOANS - In 1984 the Bank of England rescued Johnson Matthey Bank, buying it for one pound and putting in its own managers.

-- National Home Loans hit trouble in 1991 after a fall in property prices. A Bank-backed lifeboat saved NHL from collapse.

* RAILTRACK - Railtrack was put into administration -- a form of creditor protection -- in 2001 after the government lost faith with management and stopped subsidising the company.

* BRITISH ENERGY - Britain extended an emergency aid package totalling 650 million pounds in September 2002 when power prices fell below the company's production costs. In late 2003 the company's creditors signed a restructuring deal that handed them control for forgiving more than half its 1.3 billion pounds debt.

* NORTHERN ROCK - Troubles in the fifth largest mortgage lender started in mid-2007 when the credit crunch hit its ability to raise cash in money markets. The Bank of England bailed it out in Sept 2007, promising emergency funds.
