South African President P.W. Botha, at odds with his own party since suffering a stroke in January, said Thursday he plans to retire later this year after 11 turbulent years in power. Botha, 73, told Parliament that an early general election will be held at an unspecified date within the next several months. Botha did not state explicitly that he would not seek another five-year term, but he said the outgoing president would hand over the official seal to a new president following the elections. The new president is expected to be Education Minister F.W. de Klerk, who succeeded Botha as leader of the National Party on Feb. 2. Botha said he would dissolve Parliament sometime in late May and then proclaim a date for the election.
