Viviane Reding.

You have got to love European Commissioner Viviane Reding. Like a greyhound, she is immediately out of the traps pouncing on David Cameron’s rabbit. "But David, the UK supported enlargement which it could have vetoed" and again, "Any renegotiation of free movement can only be tabled by the European Commission and it has no plans to do so."

Mr Cameron’s plans are only out today and already they are in tatters.

Of course, she made clear earlier this year that Romanian and Bulgarian migrants to the UK will have the same rights to reside and draw benefits as British nationals. Unless he acts to stop mass migration from Romania and Bulgaria from January 1, 2014, what the Prime Minister is proposing does not amount to a row of beans. Nigel Farage.
