The coalition led by Romano Prodi, thanks to the electoral law which gave the winner a sixty-seat majority, can count on a good majority in the Chamber of Deputies but only on a very narrow majority in the Senate. The composition of the coalition was heterogeneous, combining parties of communist ideology, the Party of Italian Communists and Communist Refoundation Party, within the same government as parties of Catholic inspiration, The Daisy and UDEUR. The latter was led by Clemente Mastella, former chairman of Christian Democracy. Therefore, according to critics, it was difficult to have a single policy in different key areas, such as economics and foreign politics (for instance, Italian military presence in Afghanistan). In his earlier months as PM, Prodi had a key role in the creation of a multinational peacekeeping force in Lebanon following the 2006 Israel-Lebanon conflict.
