The European Union's president and foreign policy head will attend a ceremony to mark the Lisbon Treaty's entry into force, an EU Council source told RIA Novosti on Thursday.
Van Rompuy, Belgium's prime minister, was elected Permanent President of the European Council by the 27-nation bloc's leaders at a meeting on November 19, and will take office on January 1, 2010. Britain's Baroness Catherine Ashton was elected EU foreign policy chief.
The ceremony will be held in the Portuguese capital of Lisbon on December 1, the day the treaty enters into force.
European Commission President Jose Manuel Barroso and Swedish Prime Minister Fredrik Reinfeldt, whose country holds the rotating EU presidency until the end of the year, will also attend the ceremony.
On November 3, Czech President Vaclav Klaus signed the document after the country's Constitutional Court ruled that the treaty was in line with the Czech constitution. The Czech Republic was the last EU member state to ratify the treaty.
The agreement was signed in the Portuguese capital on December 13, 2007, and introduces fundamental changes to the workings of the European Union.
