Steve,
There is no FRA or EU definition of antisemitism in force now, and there has never been anything like an official one sanctioned by the EU, any official EU body or by the member states.

Yes there is.
The EUMC working definition.

Pfr,
There are racist arseholes in all groups of people, every political party,

Yes there are, but this is "recent cases of anti-Semitic abuse" which has "appalled" the NEC.
That is what Steve has denied.
