Downing Street Years - Margaret Thatcher [343]
I had one overriding positive goal. This was to create a single Common Market. The Community’s internal tariffs on goods had been abolished by July 1968. At the same time it had become a customs union, which Britain had fully accepted in July 1977. What remained were the so-called ‘non-tariff’ barriers. These came in a great variety of more or less subtle forms. Different national standards on matters ranging from safety to health, regulations discriminating against foreign products, public procurement policies, delays and overelaborate procedures at customs posts — all these and many others served to frustrate the existence of a real Common Market. British businesses would be among those most likely to benefit from an opening-up of other countries’ markets. For example, we were more or less effectively excluded from the important German insurance and financial services markets where I knew — as I suspect did the Germans — that our people would excel. Transport was another important area where we were stopped from making the inroads we wanted. The price which we would have to pay to achieve a Single Market with all its economic benefits, though, was more majority voting in the Community. There was no escape from that, because otherwise particular countries would succumb to domestic pressures and prevent the opening-up of their markets. It also required more power for the European Commission: but that power must be used in order to create and maintain a Single Market, rather than to advance other objectives.
I knew that I would have to fight a strong rear-guard action against attempts to weaken Britain’s own control over areas of vital national interest to us. I was not going to have majority voting applying, for example, to taxation which the Commission would have liked us to ‘harmonize’. Competition between tax regimes is far more healthy than the imposition of a single system. It forces governments to hold down government spending and taxation, and to limit the burden of regulations; and when they fail to do these things, it allows companies and taxpayers to move elsewhere. In any event, the ability to set one’s own levels of taxation is a crucial element of national sovereignty. I was not prepared to give up our powers to control immigration (from non-EC countries), to combat terrorism, crime, and drug trafficking and to take measures on human, animal and plant health, keeping out carriers of dangerous diseases — all of which required proper frontier controls. There was, I felt, a perfectly practical argument
