The prime minister's personal approval rating has stayed ahead of Mr Papandreou's, but if civildisorder continues for much longer that will probably slide too.
Syria has denied the allegations, saying they were "misinformation" to divert attention from civildisorder in Iraq after coalition forces took control of most of the country.
Western European governments have been more worried than Washington about the potential for civildisorder and large-scale emigration from the Soviet Union, and have been lending the nation huge sums at concessionary rates.
