I'm not talking about election campaigns, I am talking about general awareness campaigns, general communication from the EU on an ongoing basis - even if it is a straightforward web presence that can be used at national/regional level by MEPs or Parties themselves.  

My Labour candidates were explicitly pro-EU, yes.  They talked about their manifesto commitments in terms of what they wanted to achieve for Wales by being an active part of the EU.

My MEPs have sent out newsletters a few times a year to members about their work, unfortunately not more widely though.
