I am generally Euroskeptic, but I don't trust David Cameron or the Conservatives on it. The Conservatives have had a poor record on the environment and I'm worried that they want to weaken important things like environmental regulations that come from the EU, and they might succeed if they renegotiate in those policy areas.
I'd like to leave, as I see the EU in its current form as undemocratic, and I oppose in principle "ever closer union". But if leaving means risking environmental laws, then I'll tolerate the EU for now. Maybe we could leave when we have a PM and party in power that is somewhat trustworthy.
