HC Deb 26 January 1971 vol 810 c68W
Mr. Deakins

asked the Chancellor of the Exchequer if, in the negotiations for the entry of the United Kingdom into the European Economic Community, he will seek to ensure that the United Kingdom retains the right to alter the parity margins of its currency upwards or downwards.

Mr. Barber

As I told the House on 15th December, if the United Kingdom joins the Community we shall conform to whatever collective decisions have by then been taken about exchange rate margins within the Community.
