The 1999 national elections were held under a new electoral system established by a 1996 constitutional amendment. Colorado Party candidate Jorge Batlle, aided by the support of the National Party, defeated Broad Front candidate Tabaré Vázquez. The formal coalition ended in November 2002, when the Blancos withdrew their ministers from the cabinet, although the Blancos continued to support the Colorados on most issues. Low commodity prices and economic difficulties in Uruguay's main export markets (starting in Brazil with the devaluation of the real, then in Argentina in 2002), caused a severe recession; the economy contracted by 11%, unemployment climbed to 21%, and the percentage of Uruguayans in poverty rose to over 30%.
