coup of 23-F. After the failed coup, his appointment as Prime Minister was confirmed on 25 February by the vote of all the UCD members of the congress and 21 others as well, giving him a majority of 186 to 158. Splits in the UCD group led to the formation of three rival parties, the Democratic Action Party (Partido de Acción Democrática/PAD), which soon merged with the Spanish Socialist Workers' Party (PSOE), the Democratic and Social Centre (CDS) and Democratic Popular Party (PDP), resulting in the UCD being unable to count on sufficient support in the legislature. Fresh elections were called, resulting in a heavy defeat for the UCD, which won only 12 seats at the 1982 election compared to 168 in 1979. He served as Prime Minister until 1 December 1982 and was succeeded by the socialist Felipe González.
