The left? The authoritarian politicians pushing this legislation in the EU are more leftist than right.
The left, the anti-immigration parties and really, any party which isn't wholly 'let's do the same as we've always had' probably imagine that this would be used to their disadvantage somehow.

The irony.
Aside from that I also thought EU is more left than right wing right now. Nothing what they try to push this term of office seems right wing to me.
