LONDON: The UK's left-wing Green party voted Sunday to define Zionism as racism at the party's annual conference, drawing sharp backlash from three British Jewish groups, the ruling Labour Party and Israel's government.

Members of the Green party, which has five MPs in Britain's 650-seat parliament and which enjoyed a boost in recent local and special elections, backed the motion at the party's conference, with 1,022 votes in favour and 813 against.

According to the motion, Zionism would be "treated as any other form of racism" and the party supports the establishment of a "single democratic Palestinian State in all of historic Palestine".
