Prime Minister Juha Sipilä promised on Wednesday (International Women's Day) that he would allow a teenage girl to take his place as head of government for one day on October 11, 2017, in honour of the International Day of the Girl.
The girl is question is Katariina Räikkönen, a member of the children's board of the Finnish branch of Plan, an international human rights organisation. Räikkönen is a 15-year-old from Raisio,near Turku.
Plan has issued a challenge to world leaders in government and business to give their position over to a girl using the tag #GirlsTakeover.
Sipilä made the takeover announcement at an equality event in Tampere on Wednesday.
"We need more women in decision-making. It says 'Katariina is on the case' in my calendar for October 11th," Sipilä said in his speech. On Twitter he wrote: "I challenge my fellow Prime Ministers around the world to do the same."
Last year girls mobilised under Plan temporarily took over the presidency of Nepal, the Egyptian education minister's post and that of Canada's Minister of Status of Women.
The goal of the takeover is to highlight girls' opportunities and to draw attention to the fact that their rights and chances of effecting change and taking part in society are not nearly equal to those of boys.
