My jaw just dropped to the floor watching the BBC News channel - there was a headline along the lines of "Cameron is defiant amid warnings that his plan to curb EU immigration could be illegal."
"Warnings"? "Could be illegal"? There's not the slightest bloody doubt that it's illegal! This is fact, not speculation. Freedom for EU citizens to live and work in any other member state is one of the most fundamental principles of EU law - which, for the avoidance of doubt, has supremacy over UK law, and that's a principle that has been accepted and enforced by the UK courts for decades.
It's highly instructive to see the way in which the broadcasters feel they have to pussy-foot around with their use of language in respect of the UK government's antics, even when it's a matter of plain, irrefutable fact that Cameron is proposing something he has no legal power to do. Compare and contrast with the rather 'firmer' language they felt free to use only a few weeks ago in relation to scare stories about Scottish independence, no matter how fanciful those were.
