Abu Dhabi's sovereign wealth fund is to buy a 15 percent stake in London's Gatwick Airport for GBP£125 million pounds (USD$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 GBP£100 million.

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

GIP is a USD$5.64 billion infrastructure fund sponsored by Credit Suisse and General Electric.

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

GIP said on Tuesday that it planned to remain a majority shareholder in Gatwick but sell minority stakes to outside investors.
