The University and College Union, which represents around 120,000 employees, voted Wednesday to allow local branches to make a final decision on imposing a boycott on cooperation with Israeli academics.

Union members voted on a motion asking them to note that "Israel's 40-year occupation has seriously damaged the fabric of Palestinian society through annexation, illegal settlement, collective punishment and restriction of movement."

It called on British academics to condemn the "complicity of Israeli academia in the occupation."

Any future boycott would aim to prevent Israeli and British university or college staff from working on joint projects or assisting each other in their work, union spokesman Dan Ashley said.

"Every member should have the opportunity to have their say," the union's general secretary, Sally Hunt, told an annual meeting in Bournemouth, southern England.

But Hunt said she did not believe most members would support a boycott and that it would likely be difficult to enforce.

Unison, Britain's largest union, will debate a similar motion at its annual meeting in a few weeks, a spokesman said on condition of anonymity in line with union policy. The motion, which was put forward by an individual branch, calls for economic sanctions and a boycott to be applied to Israel, but the final wording was not immediately available.

Israeli Foreign Ministry spokesman Mark Regev said any boycott would be targeting the only "Middle Eastern country that has fully free and independent academia."

"We find it strange that British academics single out the Jewish state for special discriminatory treatment," Regev said.

Britain's ambassador to Israel, Tom Philips, told Israel Radio that the British government would not support a boycott.
