Education Secretary Nadhim Zahawi deserves praise for convening a summit to examine campus antisemitism, in the wake of CST figures showing a rise in incidents on campus. David Miller’s sacking was an important moment in the fight against racism, but it needs to be placed in context.

The Bristol professor’s conduct was so egregious that the longer he was left in place to spread his poison, the stronger the signal that antisemitism would be tolerated. But vital as it was that that he was removed, he was — is — far from alone in his behaviour. Over 700 academics signed a petition supporting him.

That is itself a shocking commentary on the state of academia and its embrace of antisemitic themes.

And while it is good news that the vast majority of universities have adopted the IHRA definition of antisemitism, it is a mistake to view this simple action as anything other than a basic first step. IHRA is irrelevant if campus authorities do not act against racism targeted at Jews.

Far too few appear willing to do that. That means, especially, racism by academics. Student antisemtism is certainly an important issue that needs to be tackled. But academic antisemitism is more insidious, setting the tone on campus and poisoning young minds, sometimes for life.

This is the real battle — and it is one we cannot let up on.
