=== Sebastián Piñera first administration (2010–2014)===

[[Sebastián Piñera]], the candidate of the [[Coalition for Change (Chile)|Coalition for Change]], was elected [[President of Chile|President of the Republic of Chile]] on January 17, 2010, in runoff against Senator [[Eduardo Frei Ruiz-Tagle]]. UDI and its territorial deployment was key to the  Piñera's success. Meanwhile, in [[2009 Chilean parliamentary election]], UDI managed to remain the largest party in the country and elected 40 deputies out of 120, representing the largest bank obtained by a single political party in Chile since 1990.
In August 2010 they met for the second time the lists of Juan Antonio Coloma and Jose Antonio Kast to lead the party, again with a triumph for Coloma with more than 67% of the votes.
Many members of UDI played a main role during the Piñera administration, among them were [[Joaquin Lavin]] in the ministry of education where he faced the [[2011–2013 Chilean student protests]] and the cause he had to resign in 2011, [[Pablo Longueira]] in the ministry of economy, [[Andres Chadwick]] in the ministry of interior and public security, [[Laurence Golborne]] in the ministry of mining.
The party's influence in the government forced the Piñera administration to have a conservative shift on educational, economic and cultural issues, having a moderate approach on social policy like maternity leave, taxes and civil unions for same-sex couples and directly opposing any kind of therapeutic abortion legalization. 
In the 2013 primaries the UDI candidate for the [[Alliance (Chile)]] was former economy minister [[Pablo Longueira]] in which he beat National Renewal opponent [[Andrés Allamand]], however, Longueira had to resign amid the campaign due to his depression and personal issues. The replacement of Longueira was [[Evelyn Matthei]] representing the party and the government coalition, in the first round she got the second place with a 25,03% of the votes, the right's second worst result since the return to democracy in 1990 so far, in the second round [[Michelle Bachelet]] defeated Matthei by a 25-point margin (62,17% vs 37,83%) being in relative terms the biggest margin of victory since 1994.
