The executive branch is headed by a president and vice president, and consists of a variable number (currently, 20) of government ministries. The president is elected to a five-year term by popular vote, and governs from the Presidential Palace (popularly called the Burnt Palace, ''Palacio Quemado'') in La Paz. In the case that no candidate receives an absolute majority of the popular vote or more than 40% of the vote with an advantage of more than 10% over the second-place finisher, a run-off is to be held among the two candidates most voted.
