He said: “What we actually need to do is to address the root cause of what is driving the radicalisation of people here in the United Kingdom who want to target the Jewish community.
“The government and the Charity Commission, in our opinion, have been far too slow to tackle this extremism, and if they don’t, these attacks will be planned and will be carried out again and again.”
He added that was “a grave, grave threat to the Jewish community in Greater Manchester and the UK”.
In response, Security Minister Dan Jarvis condemned “vile antisemitic terrorist attacks that target Jews simply because they are Jews” including the “horrific attack on our Jewish community in Manchester on Yom Kippur, and most recently at a Chanukah celebration in Sydney”.
He said: “Antisemitism will never have any place in our society and we are absolutely determined to stamp it out wherever it exists.
“We stand in solidarity with Jewish communities here and everywhere.”
Jarvis also praised the police and the Crown Prosecution Service, stating: “Their work has saved lives and made all of us safer.”
A Charity Commission spokeswoman said: “We take very seriously any alleged links between a charity and extremism or terrorism.
“Such links are abhorrent, and corrosive to the trust on which the charitable sector depends.
“We are robust in using the powers Parliament has granted us whenever required, dealing robustly with those who misuse charities for malign purposes including supporting extremism or terrorism.
“As the range of these threats grows, we know our powers must keep pace. We are in welcome dialogue with the government to ensure our powers and our corresponding resources are fit for the present and the future.”
