South Korea’s National Pension Service, the nation’s biggest investor, said it is interested in buying HSBC Holdings Plc’s headquarters building in London.

No 'detailed' talks have taken place, Kim Ha Young, a spokesman for the Seoul-based agency, said today by phone. The Maeil Business Newspaper reported earlier the pension fund is in negotiations to buy the building from HSBC, without saying where it got the information.

A South Korean consortium is competing with a group of Malaysian investors to buy the building for as much as £800m ($1.26bn)
