My MEP where I previously lived was Nigel Farage.
I wrote to him on this issue (via the BALPA template with my own bit added) and lets just say his response was rather robust.
At the time I thought he came across as rather dis-interested and not particularly receptive to my email. He basically said regardless of how much (and regardless of how many) we lobby through our MEP's the Euro parliament will push through what they want regardless.
I found this rather harsh. His closing line (predicatably) was along the lines of "if you want real change, we need to exit the EU at a legislative level" He then suggested I vote UKIP to see to this.
In the light of todays news....fair point Nigel. :-(
