LONDON (Reuters) - Citigroup (C.N: Quote, Profile, Research), which unveiled a radical overhaul earlier this month, could cut almost a quarter of jobs in its UK consumer business as it focuses on its Citi and Egg brands, closing off lending through two other units.

The U.S. banking giant said on Monday it would stop new lending through Future Mortgages, a mortgage intermediary, and CitiFinancial, a personal loans business, after a review of its UK consumer arm as part of the group's global shake-up.

Both units have a UK market share of less than 1 percent.

A Citi spokeswoman said Future Mortgages and CitiFinancial currently have some 700 employees between them, 400 of those employed at its Doxford office in northeast England and the remainder through CitiFinancial's loan centers. Both the branch network and the office are due to be shuttered, the bank said.

Citi's UK consumer arm currently employs some 3,000 people.

"Future Mortgages and CitiFinancial were not identified as areas for strategic growth," Bert Pijls, business manager for Citi's UK consumer business, said in a statement.

He said the move reflected global strategy and would create "a platform for expansion in the UK personal finance market".

Citigroup said earlier this month it planned to shed $400 billion of assets worldwide to restore profitability after huge losses tied to the mortgage and credit markets.

Citi came under fire in Britain earlier this year after it wrote to 161,000 Egg customers -- 7 percent of the total -- cancelling their cards. It was forced to deny the move was an excuse to exclude unprofitable customers.
