Who said Shah was anything Dave?
She made some anti-Semitic statements according to the Labour leadership and her own admission.
She attributed it to her own ignorance and says she now knows better.

You asked me to speculate on why this issue has come to prominence.
That is all I did.
My case is that it is an issue for Labour, not why.
The Labour leadership agree with me, but Steve and Jim think that they know better.
How silly that makes them look!
