I don't quite get what you mean? EPP is technically in power (whatever that means in the European Parliament). But also why would that matter? Or they wanted to force a vote just so they could vote against it (which is not necessarily a stupid strategy in cases like this)?
No, that's not what it means. Actually, it doesn't _really_ mean anything, here, as it's not correct. The EPP has 188 seats out of 720. It is the largest single party, but, ah, to some extent, so what.
(Also it is a European Parliament party, not a _real_ political party. It's not a cohesive unit and has no leadership; it's pretty much just a grab-bag of member state parties.)
