 De Klerk declared that he would lead the National Party in vigorous opposition to Mandela's government to ensure "a proper multi-party democracy, without which there may be a danger of South Africa lapsing into the African pattern of one-party states".In de Klerk's view, his greatest defeat in the negotiations with Mandela had been his inability to secure a blanket amnesty for all those working for the government or state during the apartheid period.De Klerk was unhappy with the formation of the Truth and Reconciliation Commission (TRC).
