The lower house of Spain's parliament has voted to ratify the European Union constitution.
The document still must be approved by the Senate, 311 of the 350 members of the Congress of Deputies voted in favor of it. Spanish voters had already approved it in a referendum.
The EU constitution will be the subject of talks Thursday between Spanish Prime Minister Jose Luis Zapatero and his Irish counterpart, Bertie Ahern in Madrid.
Their talks are also expected to include the future financing of the EU and the status of minority languages such as Gaelic and regional Spanish languages.
The Irish prime minister is also expected to lay a wreath at the memorial to the victims of last year's terrorist bomb attacks in Madrid.
