to 1988, he rallied Europe to the call of the single market, and when appointed to a second term he began urging Europeans toward the far more ambitious goals of economic, monetary and political union." But Delors not only turned the Community around, he signalled a change in the Presidency. Before he came to power, the Commission president still was a position of first among equals; when he left office, he was the undisputed icon and leader of the Community. His tenure had produced a strong Presidency and a strong Commission as the president became more important. Following treaties cemented this change, with the president being given control over the allocation of portfolios and being able to force the resignation of Commissioners. When President Romano Prodi took office with the new powers of the Treaty of Amsterdam, he was dubbed by the press as Europe's first Prime Minister. President Delors' work had increased the powers of the Parliament, whose support he had enjoyed. However, later Commissions did not enjoy the same support, and in 1999, the European Parliament used its powers to force the Santer Commission to resign. Parliamentary oversight Historically, the Council appointed the Commission president and the whole body by unanimity without input from Parliament. However, with the Treaty on European Union in 1993, the European Parliament, the body elected directly by the citizens of the European Union, gained the right to be consulted on the appointment of the president and to veto the Commission as a whole. Parliament decided to interpret its right to be consulted as a right to veto the president, which the Council reluctantly accepted. This right of veto was formalised in the Amsterdam Treaty. The Treaty of Nice changed the Council's vote from a unanimous choice to one that merely needed a qualified majority. This meant that the weight of the Parliament in the process increased resulting in a quasi-parliamentary system where one group could be in government. This became evident when numerous candidates were put forward in 2004, and a centre-right vote won out over left-wing groups, France and Germany. José Manuel Barroso, elected Commission president that year, was then forced to back down over his choice of Commissioners, owing to Parliament's threat that it would not approve his Commission. In 2009, the European People's Party (EPP) endorsed Barroso as its candidate for Commission president, and the EPP subsequently retained its position
