On 29 October 2004, the heads of state and government of the 25 European Union member states will sign the treaty for a European constitution. The formal signing will conclude the Intergovernmental Conference ? the second of the three stages on the path to an EU constitution. The Intergovernmental Conference was preceded by the European Convention, which developed a draft constitution between February 2002 and July 2003. The president of the Convention, Valéry Giscard d?Estaing, delivered this draft to the then president of the European Council, Silvio Berlusconi, on 18 July 2003.
