"Staying in the EU increasingly takes power away from local people and hands it to unelected commissars - remember MEPs only vote to pass laws, they don't propose them."
Sorry - but i just don't see your logic.
The EU is made up of 7 institutions, but lets focus on the 4 main ones of the European council, the council of the EU, the EU parliament and the EU commission.
The european council is made up of the heads of state of each member country. our representitive here is David Cameron. He was elected by the UK public.
The council of the european union is made up of the relevant ministers of each member state and you voted for them too - although their position on the council is dependent upon them holding a cabinet position - so it is a little different, but basically they too were elected by the UK public and then put forward for the position by their party leader (so David Cameron picks George Osbourne as chancellor and as long as he is chancellor, then he is on the council of europe). He is an elected MP, the UK public voted for him.
The european parliament has directly elected members and the electoral system is different to the first past the post system that you see in westminster elections, but the MEPs are elected by the UK public. We typically have a very poor turn out in European elections, but just because you didn't vote for one doesn't mean that they were not fairly elected by the UK public.
Finally, you have the european commision. people are appointed to the commission by the leader fo their country (so in this case, David Cameron). As with many other things, when you elect someone to parliament, you effectively say that they represent you and you trust them to make decisions that you would (broadly) support. This is another one of those situations. The comissioners are not directly elected, but the person appointing them is.
couple of important points:
1) the councils provide general direction on what the EU wants to get done and represent the government view
2) the comission is full of technical people who come up with ways of doing what will support the general direction as set by the council
3) the parliament represent the people of Europe and vote on that legislation
People seem to have a problem with the comission, but i don't understand why. They are doing a very similar role the the Civil service in the UK, who are completely unelected.
That make anything clearer?
