Protest votes that can undermine the economic and possibly the social stability of both the UK and the EU are an irresponsible move.
In fact, there was plenty of evidence that many people who voted to leave in the referendum only did so to as a protest against Cameron's Government. Look where that got us and what it has cost the UK so far!
So what will the role of any elected Brexit MEPs be, I wonder. Will they have served their purpose once elected, will they try to cause chaos in the UU Parliament, or will they actually play an active, responsible role, representing the best interests of the whole of the UK, for as long as we remain in the Union?
