In the grand scheme of things, £3 million a year from the overall public spending total is barely worth mentioning. But as extra funding for synagogue security, it could be of critical importance. It could save lives. So the Prime Minister deserves enormous credit for ensuring that the JC's Secure Our Synagogues campaign - itself based on a recommendation of the All-Party Parliamentary Inquiry into Antisemitism - achieved its aim within just four weeks.

We wrote at the launch that "this should not be controversial, and we have little doubt that the government will support it". We contacted all 650 MPs and our journalists raised the campaign at every opportunity with ministers and key figures. Responding to those efforts, alongside the work of CST and the APPG's report, Mr Cameron has provided genuine leadership in ensuring that communal security is a key priority.
