The main Liberal Party becomes oppositor to Uribe's government, while all pro-Uribe members of the liberal party join other parties. The New Party (Nuevo Partido) is formed to unite all pro-Uribe liberals, however, not all of them join this group, as some of them joined Radical Change Party. Most of the previous factions unite in only three parties: Democratic Colombia Party, Living Colombia Movement and Citizen's Convergence Party. 2006: The New Party, along with some members of the liberal party, some of Radical Change, minor liberal and independent movements, plus a small group of conservatives, form the Social National Unity Party, most known as Party of the U, which is currently the biggest party of Colombia. Radical Change Party grows with the fusion with independent liberal and Christian movements. Other three liberal small parties had representation: Democratic Colombia Party, Living Colombia Movement and Citizen's Convergence Party. 2010: Half of the parliamentaries from Radical Change Party switch to Party of the U. The three small liberal movements (Democratic Colombia Party, Living Colombia Movement and Citizen's Convergence Party) unite to become the National Integration Party (PIN).
