UPDATE 1-Abu Dhabi wealth fund to buy Gatwick stake -Times

(Adds GIP spokesman declined comment)

LONDON Feb 4 (Reuters) - Abu Dhabi's sovereign wealth fund is to buy a 15 percent stake in London's Gatwick Airport for 125 million pounds ($198.4 million) as the airport's new owner aims to bring in additional investors, the Times newspaper reported in its online edition on Thursday.

The Abu Dhabi Investment Authority's planned investment in London's second-biggest airport comes two days after South Korea's National Pension Service said it planned to buy a 12 percent stake in Gatwick for about 100 million pounds.

A spokesman for Global Infrastructure Partners (GIP), which acquired Gatwick last year for 1.5 billion pounds, declined to comment on the report.

GIP is a $5.64 billion infrastructure fund sponsored by Credit Suisse (CSGN.VX) and General Electric (GE.N).

The Abu Dhabi Investment Authority is considered the world's biggest sovereign wealth fund and believed to have assets of $500 billion to $700 billion.

GIP said on Tuesday that it planned to remain a majority shareholder in Gatwick but sell minority stakes to outside investors. ($1=.6299 Pound) (Reporting by Susan Fenton; Editing by Leslie Adler, Gary Hill)
