Dave used last night’s champagne fuelled Tory summer ball to go off on one about terrorists and mass surveillance.

Speaking to a 850 strong crowd at a packed Hurlingham Club, Cameron said he was all for Muslims who call out and condemn terror, but argued that he sees it as his mission to tackle any violent ideology.

First in his sights who those that say things like “I don’t condone terror, but a caliphate is a good thing” or that we bring terrorism on ourselves and it’s all our fault because of Iraq and Afghanistan, Israel, or poverty in Muslim countries.

An emotional Cameron got things stirring by declaring that we can’t sit idly by as even if we left them alone they’re not going to leave us alone, they’ll come and destroy us and our way of life using the only methods they know.

Witnesses report he then went on a passionate defence of data gathering – having a dig at those who think the government is overreaching/turning into Big Brother.

The PM’s shaky justification for mass-surveillance was that we have always tapped phones and intercepted letters of organised criminals and the IRA, now that technology has moved on, we need to react.

Iffy: bugging Seamas O’Bomber’s landline is somewhat different from reading everyone’s emails.

It’s safe to say the civil liberties lobby were not out in force at the £450 per head event.
