Dave,
Antisemitism is a crime in the UK. If it happened there would have been a criminal investigation followed by arrests and convictions.

No. There is discretion. Shah admitted making anti-Semitic comments, but could not be accused of stirring up hatred.
"Antisemitism, as such, is not a criminal offence."

That stupid Tory woman was not arrested for using the most racist of all words.
