Mr Freer asked that with instances of antisemitism on the rise, did Mr Cameron agree that it should be rooted out from all organisations, whether public or private.
The Prime Minister replied: “Antisemitism is an absolute cancer in our society and we should know when it grows it is the signal of even worse things happening.
“There is sadly a growth of antisemitism in our country and we see it in terms of attacks on Jewish people and Jewish students.”
Mr Cameron was speaking after a series of new revelations about antisemitism in Labour, involving the suspension of two local councillors, and claims that most Jewish Labour MPs had been catagorised as "hostile" to Mr Corbyn in a list allegedly drawn up by the Labour leader.
