UNITARIAN DEMOCRATIC COALITION

The 'Unitarian Democratic Coalition' (Portuguese: Coligação Democrática Unitária or 'CDU') is an electoral and political coalition between the Portuguese Communist Party (Portuguese: Partido Comunista Português or 'PCP') and the Ecologist Party "The Greens" (Portuguese: Partido Ecologista "Os Verdes" or 'PEV'). The coalition also integrates the political movement named Democratic Intervention (Portuguese: Intervenção Democrática or 'ID')
The coalition was formed for the first time in 1987 in order to run to the simultaneous legislative election and European Parliament election that were held in July 19 of that year.
The present symbol of CDU shows the PCP's symbol and the PEV's symbol, an hammer and sickle and a sunflower, respectively, with the respective names below. That symbol replaced a former one that featured three hexagons with the inscription: CDU (as shown in the sticker below) and was often used with a bee. That was sometimes said to mean that CDU worked just like a bee (collectively and every day) and the hexagons were meant to represent the cell-based Leninist organization of the PCP.
Since the beginning of the coalition, the parties never participated separated in any election. The Communist Party is the major force inside it and gathers the majority of the places in the electoral lists, however, the greens also have an important presence and elected 2 Members of the parliament among the total 14 elected by the coalition in the last legislative election. Each party has its own parliamentary group and counts as a separate party in official issues.
At a local level, the coalition usually presents lists in almost every municipality and both Communists and Green may occupy the first places in the lists. As the Greens have a smaller structure, the offices of the Communist Party are used as offices of the coalition.
The coalition has a youth wing, called Juventude CDU, that develops political work in youth related subjects, along with youth oriented activities, mainly during the electoral campaigns. The Juventude CDU is mainly composed by members of the youth wings of the parties that compose the CDU, the Portuguese Communist Youth and the Ecolojovem.
