My opinion hasn't changed and is very unlikely to change before May. I believe that we're better off in the EU. It's not perfect and I'd love to see the UK take the lead on fixing what's wrong. Why throw away something that can be fixed?
I worry that the UK will never be able to take a leading role in Europe though. A significant number of British people vote for UKIP in European elections, whose MEPs have a dreadful attendance record, and thus our voice is diminished. Ultimately, that's why I'll be fairly happy even if we do vote to leave.
