Thatcher Cautions Common Market on Unified Europe Plan

BRUGES, Belgium — Prime Minister Margaret Thatcher said Tuesday that Britain will resist the European Communities’ plan to abolish all internal border controls.

In a speech at the College of Europe in the medieval Flemish city of Bruges, Thatcher painted a vision of extending to the Common Market as a whole her domestic crusade to cut back the role of government and promote private enterprise.

And although she enthusiastically endorsed the drive to create a united Common Market free of trade barriers by the end of 1992, she ruled out political integration that would weaken the national sovereignty of the 12 member states.

“We have not successfully rolled back the frontiers of the state in Britain, only to see them reimposed at the European level, with a European ‘superstate’ exercising a new dominance from Brussels”--the European Communities’ headquarters--she said.
