A UAE investor is interested in buying a 10 per cent stake in National Bank of Kuwait (NBK), the country's biggest lender. "It has been said that a UAE investor wants to buy (the stake)," Kuwaiti daily Al Qabas said citing sources. Earlier in August the newspaper reported that at least two shareholders of NBK received offers to sell a 10 per cent stake in the bank. A spokesman for the bank said then that NBK had not been reached or contacted by any party. "Companies who have enough amounts of shares, are being polled to know their readiness to give up these shares, prior to getting into any agreements or official procedures," the report said on Sunday. In March, NBK's shareholders approved a 10 per cent capital increase through a rights issue to fund expansion.
