 From May to July 1970, the Liberal city manager of Helsinki, Teuvo Aura, led a caretaker government.Long-time Foreign Minister Ahti Karjalainen managed to form a new centre-left majority government in July 1970, which excluded the National Coalition Party and Rural Party from power.One notable demographic change of these parliamentary elections was the election of several young (under 30-year-old) MPs reflecting the rising political activity of young Finns (the baby boomers), and the lowering of minimum voting age to 20 years.
