@hawkeye10,
No, (although I don't want to put words in his mouth)Walter seems to be arguing that you don't understand news reports, which is about par for the course. You thought the SNP were a right wing party after all.
We are going to be having a referendum on EU membership and businesses are setting out what they think the consequences of an EU exit are. There will be a lot more of this in the run up to the referendum.
Big firms by and large want to stay in, some small firms want to leave in the mistaken belief it will cut down on red tape. If anything it will have the opposite effect, if we want to continue trading with Europe we'll have to follow their regulations. Being outside the EU will mean we have no say over those regulations, and will probably mean more red tape as outsiders.
Immigration is another no brainer, Switzerland is outside the EU but a member of the European Free Trade Association. It has tried to limit the free movement of labour and is now subject to sanctions which will get steadily tougher. Britain will face the same consequences if it tries to limit free movement unilaterally regardless of whether or not we stay in the EU.
