DAVOS-No need to worry over Spain, Portugal -OECD's Gurria

DAVOS, Switzerland Jan 27 (Reuters) - Spain and Portugal are unlikely to need to restructure their debt and a plan to stabilise Spain's savings banks is likely to work, the head of the Organisation for Economic Cooperation and Development (OECD) said on Thursday.

"One country may need restructuring, that is Greece. I'm not worried about Spain and Portugal; they are treated unfairly by the markets," Gurria told Reuters Insider television on the sidelines of the annual World Economic Forum meetings.

On Japan, he added its debt problem was not new and a ratings downgrade would make things worse.

Rating agency Standard & Poor's cut Japan's long-term sovereign debt rating on Thursday for the first since 2002, saying the country's government lacked a coherent plan to tackle its mounting debt.
