In 2018 the party regained the name of the Radical Party.
bThe percentage of seats held by a party in each elected body is multiplied by a weighting factor, which is equal to the inverse value of that body's total seats divided by the summation of the inverse values of all bodies' total seats. The resulting weighted percentages are then summed together to obtain a party's "weighted representation" value. (Formula: [S/43^2+D/155^2+R/278^2+M/345^2+C/2224^2]/T, with T=1/43+1/155+1/278+1/345+1/2224, S=party senators, D=party deputies, R=party regional advisors, M=party mayors, C=party councilmen.)
