ONLY 12 Labour activists have been expelled for anti-Semitism since the party's racism crisis erupted, it emerged today.

Just 1.8 per cent of the party members accused of anti-Jewish hatred have been kicked out by Labour bosses.

Hundreds have been allowed to stay in the party despite being found guilty of racism by an internal probe.

The bombshell figures were revealed in a letter from Labour's general secretary to party MPs.

Corbyn ally Jennie Formby confirmed that since last April, 673 party members have been formally accused of anti-Semitism.

Roughly a third were found to be innocent after an investigation, while nearly 200 were let off with a slap on the wrists.

Just 42 have been referred to the party's National Constitution Committee, which is the only body empowered to expel members.

Of those, 12 were kicked out and six received unspecified "sanctions", Ms Formby said.

There are dozens of cases still being investigated - while 49 members quit the party before they could be disciplined.

WEB HATE EPIDEMIC
Most of the activists accused of racism were reported after posting anti-Semitic material online, according to Labour sources.

The party received another 400 reports which related to people who turned out not to be Labour members.

The stats date back to April last year - when the scandal burst into the open as dozens of MPs staged a protest against Jeremy Corbyn's handling of anti-Semitism in the party.

In her letter to MPs, Ms Formby admitted that Jewish groups are still refusing to work with Labour because they're so furious about the way the party has managed the crisis.

The data released today was published after MPs lobbied party chiefs to be more transparent about the disciplinary process.

But veteran MP Margaret Hodge insisted the figures play down the the true scale of the problem.

She blasted: " I alone put in over 200 examples, some vile, where evidence suggested they came from Labour.

"So don’t trust figures. Can’t believe only 12 expulsions. Not convinced leadership serious on rooting out anti-Semitism."

A Labour spokesman said: “Jennie Formby has published the figures on anti-Semitism complaints handled by the party and published a report on the work the party has done and is doing to speed up and strengthen our procedures, increasing transparency.

"These figures relate to about 0.1 per cent of our membership, but one anti-Semite in our party is one too many. We are committed to tackling anti-Semitism and rooting it out of our party once and for all.”

Last year saw anti-Semitism in Britain rise to a record level, partly driven by the Labour epidemic, according to recent figures.

The scandal flared up afresh last week as Jewish MP Luciana Berger faced a bid to kick her out of her Liverpool Wavertree seat.
