 Nonetheless, the prevalence of two big parties overall has been eroded and the need for coalitions appears to be the new normal since around 2015.Since the 1989 election, there have been 4 coalition governments, all including at least both the conservative National Party and the liberal Colorado Party.The first one was after the election of the blanco Luis Alberto Lacalle and lasted until 1992 due to policy disagreements, the longest lasting coalition was the Colorado-led coalition under the second government of Julio María Sanguinetti, in which the national leader Alberto Volonté was frequently described as a "Prime Minister", the next coalition (under president Jorge Batlle) was also Colorado-led, but it lasted only until after the 2002 Uruguay banking crisis, when the blancos abandoned the government.
