Consolidated version of the Treaty on the Functioning of the European Union

Article 140 U.K. (ex Articles 121(1), 122(2), second sentence, and 123(5) TEC)

1. At least once every two years, or at the request of a Member State with a derogation, the Commission and the European Central Bank shall report to the Council on the progress made by the Member States with a derogation in fulfilling their obligations regarding the achievement of economic and monetary union. These reports shall include an examination of the compatibility between the national legislation of each of these Member States, including the statutes of its national central bank, and Articles 130 and 131 and the Statute of the ESCB and of the ECB. The reports shall also examine the achievement of a high degree of sustainable convergence by reference to the fulfilment by each Member State of the following criteria:

• the achievement of a high degree of price stability; this will be apparent from a rate of inflation which is close to that of, at most, the three best performing Member States in terms of price stability,

• the sustainability of the government financial position; this will be apparent from having achieved a government budgetary position without a deficit that is excessive as determined in accordance with Article 126(6),

• the observance of the normal fluctuation margins provided for by the exchange-rate mechanism of the European Monetary System, for at least two years, without devaluing against the euro,

• the durability of convergence achieved by the Member State with a derogation and of its participation in the exchange-rate mechanism being reflected in the long-term interest-rate levels.

The four criteria mentioned in this paragraph and the relevant periods over which they are to be respected are developed further in a Protocol annexed to the Treaties. The reports of the Commission and the European Central Bank shall also take account of the results of the integration of markets, the situation and development of the balances of payments on current account and an examination of the development of unit labour costs and other price indices.

2. After consulting the European Parliament and after discussion in the European Council, the Council shall, on a proposal from the Commission, decide which Member States with a derogation fulfil the necessary conditions on the basis of the criteria set out in paragraph 1, and abrogate the derogations of the Member States concerned.

The Council shall act having received a recommendation of a qualified majority of those among its members representing Member States whose currency is the euro. These members shall act within six months of the Council receiving the Commission's proposal.

The qualified majority of the said members, as referred to in the second subparagraph, shall be defined in accordance with Article 238(3)(a).

3. If it is decided, in accordance with the procedure set out in paragraph 2, to abrogate a derogation, the Council shall, acting with the unanimity of the Member States whose currency is the euro and the Member State concerned, on a proposal from the Commission and after consulting the European Central Bank, irrevocably fix the rate at which the euro shall be substituted for the currency of the Member State concerned, and take the other measures necessary for the introduction of the euro as the single currency in the Member State concerned.
