The survey, conducted in October, of 500 people from each of the EU's member nations included a list of 15 countries with the question, 'tell me if in your opinion it presents or not a threat to peace in the world'. Israel was reportedly picked by 59 per cent of those interviewed.

The leaking of the results of the poll to El Pais and the International Herald Tribune has sparked a bitter row, with a major Jewish human rights and lobbying group, the Simon Wiesenthal Centre, demanding that the EU be excluded from the Israel-Palestinian peace process and accusing Europe of suffering the worst outbreak of 'anti-semitism' since World War Two.

The results appear to be a mark of the widespread disapproval in Europe of the tactics employed by the government of Ariel Sharon during the present intifada.

Israeli Ministers and spokesman have also been at pains recently to insist that a definition of modern 'anti-semitism' should include criticism of the way the state of Israel chooses to protect itself, defining that criticism as an overt attack on Israel's survival.

Members of the Sharon government have bridled at the efforts of Tony Blair and UK officials to try to mediate between the two sides. At one stage journalists were briefed that Israel regarded the Foreign Office as having an 'Arabist' bias.

Reacting to the poll, the Simon Wies enthal Centre, which claims 400,000 members in the US alone, has begun ordering a petition to condemn the European Commission and demand the EU no longer be represented in the so-called Quartet group trying to mediate an end to violence between Israel and Palestine.

The poll also comes against a background of an increase in anti-semitic attacks in Europe in the past year, although the evidence in countries such as France suggests that many are being committed by young Islamists.

'This poll is an indication that Europeans have bought in, "hook, line and sinker", to the vilification and demonisation campaign directed against the state of Israel and her supporters by European leaders and media,' said Rabbi Marvin Hier, the Wiesenthal Centre's founder.

'This shocking result that Israel is the greatest threat to world peace, bigger than North Korea and Iran, defies logic and is a racist flight of fantasy that only shows that anti-semitism is deeply embedded within European society, more then at any other period since the end of the war,' he added.
