The cause of her ire is that the French have been bundling Romanian gypsies out of the country. The French have about 300 major gypsy camps; each with several hundred occupants and each the malignant centre of a local crime wave. It's not surprising the French want rid.
And in fact under EU law the French are entitled to kick them out. That's not Ms Reding's beef. She's complaining that each gypsy isn't being considered individually, with a personal assessment for each potential deportee. Instead the French government is rounding them up, giving each one a €160 grant and busing them home to Romania.

Of course Sarky's got skin in the game now and can't be seen to back down. But the harpy has the law on her side and France may end up paying a fine to the EU commission.
