Maastricht Treaty - Ratification

Ratification

The process of ratifying the treaty was fraught with difficulties in three states. In Denmark, the first Danish Maastricht Treaty referendum was held on 2 June 1992 but a shortfall of fewer than 50,000 votes resulted in the treaty not being ratified. After the failure, alterations were made to the treaty through the addition of the Edinburgh Agreement which lists four Danish exceptions. The treaty was eventually ratified the following year on 18 May 1993 after a second referendum was held in Denmark.

In September 1992, a referendum in France only narrowly supported the ratification of the treaty, with 51.05% in favour. Uncertainty over the Danish and French referendums was one of the causes of the turmoil on the currency markets in September 1992, which led to the UK pound's expulsion from the Exchange Rate Mechanism.

In the United Kingdom, an opt-out from the treaty's social provisions was opposed in Parliament by the opposition Labour and Liberal Democrat MPs and the treaty itself by the Maastricht Rebels within the governing Conservative Party. The number of rebels exceeded the Conservative majority in the House of Commons, and thus the government of John Major came close to losing the confidence of the House.
