(Brussels) On Saturday, 25 March, “we will celebrate the 60th anniversary of the signing of the Treaties of Rome”. “We have agreed to celebrate together the beginning of a long journey at the Orazi and Curiazi Hall of the Capitol, the very place where the Treaties were signed in 1957. This will be an opportunity to reflect on the state of the European Union and the future of the integration process”. The President of the European Council, Donald Tusk, wrote this in his invitation letter to the EU heads of state or government who will all attend the event at the Capitol (with the exception of British Prime Minister Theresa May). The celebration will be attended by heads of state or government and the presidents of the European Parliament, the European Council, and the Commission. “First, this will be an opportunity to celebrate our history together and take stock of sixty years of integration. It is no secret that the historical moment we are facing requires deeper and more solid reflection on the challenges for the Union”. After the celebratory session, “we intend to adopt a political declaration reaffirming the validity of the European integration project”. The programme starts today at 3.30pm with a Social meeting between the EU, trade unions and business associations. The audience with Pope Francis is at 6pm. On Saturday, the ceremony will start at 10am. It will be followed by a press conference, a luncheon hosted by the President of the Italian Republic Sergio Mattarella, and then participation in the March for Europe.
