Answer
In the 2016 party conference, Stubb lost to Petteri Orpo, who became the new leader of the National Coalition Party in Finland. Orpo, who had served as the Minister of Finance, represented a more centrist and pragmatic approach compared to Stubb's pro-European and business-oriented policies. The leadership change reflected a shift in the party's priorities towards addressing domestic concerns and strengthening the party's position in the Finnish political landscape.
