South Africa's permanent representative to the United Nations and presented his credentials to Secretary-General Kurt Waldheim on 15 October 1974; in November of that year, however, South Africa was suspended from membership of the General Assembly and, over the ensuing years, the country was excluded from official participation in virtually all of the UN's organs and agencies. Politician In the elections of 1970 and 1974, Botha was elected to the House of Assembly as MP for Wonderboom in the Transvaal. In 1975, he was appointed South Africa's Ambassador to the United States, in addition to his UN post. In 1977, he re-entered Parliament as MP for Westdene, and was appointed minister for foreign affairs by Prime Minister B. J. Vorster. He continued to represent Westdene for the remainder of his political career. Botha entered the contest to be the leader of the National Party in 1978. He was allegedly considered Vorster's favourite and received superior public support among whites (We want Pik!) but withdrew after criticism concerning his young age, lack of experience (having spent 16 months as foreign minister) and alleged liberal beliefs as opposed to the ultra-conservative NP machinery (in which he lacked a significant position), instead throwing his support behind P. W. Botha, who was ultimately elected. In 1985, Botha helped to draft a speech that would have announced common decision-making on all levels in a single constitutional unit and a formula for bringing about the release of Nelson Mandela, but this draft was rejected by P. W. Botha. The next year, he stated publicly (during a press conference in Parliament, asked by German journalist Thomas Knemeyer) that it would be possible for South Africa to be ruled by a black president provided that there were guarantees for minority rights, but was quickly forced to acknowledge that this position did not reflect government policy. Botha recalled in 2011 that he had been "severely reprimanded and almost fired" over his remarks. In early 1986 he was also an instrumental figure in the South African government's negotiations with the Commonwealth Eminent Persons' Group (EPG). Although the Group's mission was aborted after the South African Military launched cross-border raids on ANC bases on 19 May, in the preceding months Pik Botha had engaged in extensive talks with the Group about a possible path to negotiations, including calls for a suspension of violence and the unbanning of the ANC.
