You know as well as I do that I could pull up loads of links to CBI (Confederation of British Industry) reports that stress the importance of our continued EU membership and you could probably come back with links giving a counter argument, so let's no bother
All i would say is that personally i'll go with the CBI over the UKIP fantasists on the right who dream of a lost world of global empire and believe we can walk away from the successful trading block on our doorsteps.
