[1] Prime Minister Ahti Karjalainen's centre-left coalition government lost the Finnish People's Democratic League in March 1971 as they opposed the removal of government subsidies from certain foods whose prices rose, and was forced to resign in October 1971, due to the disagreements between the Social Democratic Party and the Centre Party over the amount of agricultural subsidies.

According to some historians, politicians and journalists, such as Allan Tiitta, Seppo Zetterberg, Johannes Virolainen, Veikko Vennamo and Pekka Hyvärinen, an underlying reason for these early parliamentary elections was President Urho Kekkonen's desire to continue in office without regular presidential elections which had been scheduled for 1974.

Re-election as President through exceptional means would require a five-sixths majority in Parliament and, according to the above analysts, Kekkonen hoped that such early elections would reduce the number of Finnish Rural Party MPs, and would thus make the exceptional electoral law's passage in Parliament easier.

Kekkonen remembered bitterly the loud and constant criticism of himself and of his foreign policy that Rural Party leader Veikko Vennamo had practised during the 1968 presidential election campaign, and he was determined not to submit himself to such a vicious election campaign this time.

Government formation was difficult due to partisan bickering and the elections' rather inconclusive results.
