LONDON (JTA)—Anti-Semitic incidents either soared in Great Britain last year, dipped a bit or dropped significantly—it depends whom you ask.

A new report published by a Jewish organization said there were 594 incidents, the most since records started being kept in 1984. That represents a 31 percent increase over the prior year, according to the annual report by the Community Security Trust.

That’s in sharp contrast to the London Mayor’s Office, where Lee Jasper, director of Equalities and Policing, reported that anti-Semitic attacks decreased sharply in the past year.

Then the Israel-based Global Forum against Anti-Semitism, chaired by the Foreign Affairs Ministry, reported that anti-Semitic incidents in the United Kingdom had fallen by 3 percent, to 312 in 2006 from 321 the year before.

The Jewish Chronicle, the U.K.’s national weekly newspaper, reported that the Community Security Trust “rebuked” Israeli Foreign Minister Tzipi Livni for “grossly” underestimating the level of anti-Semitism in the United Kingdom. A letter sent to Livni said the Israeli figures “were wrong” and the reported fall is “a grossly inaccurate portrayal of the situation in the U.K.”
