Not sure I agree with his “rightwing, nationalist escapism”. comment, seems it is just the latest form of the ancient and overused comment that it is 'racist' to even discuss immigration.
But this is also what he said,
/// Free movement of immigrants in the EU is needed to run a market economy and restrictions should not go further than curbs on access to benefits or the NHS, Mr Clarke said. ///
And one has to agree that there should be curbs imposed on the access to benefits, and the NHS, and regarding this both Labour and the Lib-Dems also agree with Ian Duncan Smith's suggestions.
/// It came as Labour and the Liberal Democrats backed calls from Conservative ministers for tougher limits on European Union migrants' rights to claim benefits in Britain. ///
/// Nick Clegg, the Lib Dem leader, said Mr Duncan Smith's idea was "eminently sensible". ///
I think that if the 'carrot' was withdrawn, we would see immigration brought down to a mere trickle.
