From the same piece in Labour List.

"Shami Chakrabarti, who will be chairing a wider ranging inquiry looking at anti-Semitism within the Labour Party. The entire NEC recognises the seriousness of this issue and is committed to addressing all the issues raised by these inquiries. "

So all you people who claim that antisemitism within Labour is not a serious issue are directly contradicted by the Labour Party National Executive committee who say it is, and they are appalled by recent antisemitic abuse.
