 The veteran Centrist politician Johannes Virolainen claimed in his memoirs that Kekkonen had appointed Koivisto as Prime Minister on the advice of former Prime Minister Miettunen, who claimed that the Finnish people would then see that Koivisto was not as intelligent as they had believed him to be.Kekkonen's official biographer, historian Juhani Suomi, disagreed, and claimed that Koivisto was Kekkonen's last remaining choice as Prime Minister – unless Kekkonen had intended to appoint a caretaker government.Koivisto's second – and final – government would last, despite frequent internal disagreements (their background was Kekkonen's imminent resignation as President and Koivisto's supreme popularity as his successor), until February 1982.
