London: Gold gained for the first time in four days in London as concern about Greece's debt crisis spurred demand for the metal as a protection of wealth.

European Central Bank Executive Board member Juergen Stark said in an interview with Die Welt newspaper that he doesn't expect the international community to finance Greece further after July if the country doesn't implement its austerity plan.

Gold touched $1,490.85 an ounce, the lowest level since May 20.

"We would not be surprised to see a pick-up in safe-haven interest in the short term," William Adams, an analyst at Basemetals.com in London, said today in a report.

"Given the uncertainty over Greece, we are surprised they have not attracted more safe-haven buying," he said, referring to gold and silver.

Greek Prime Minister George Papandreou called on lawmakers to obey their "patriotic conscience" and back tougher austerity measures, as they began to debate a five-year budget plan on Monday.
