Sanna Marin was formerly prime minister of Finland and leader of the country’s Social Democratic Party. She joined the Tony Blair Institute for Global Change in September 2023 as a strategic counsellor, where she works with colleagues and teams across TBI’s portfolio of countries, advising political leaders on their reform programmes. She has a record of accomplishment, from setting one of the world’s most ambitious climate targets – enabled by a full programme of digitalisation and deployment of technology – to shepherding her country’s accession to NATO following Russia’s aggression in Ukraine (the swiftest accession in the alliance’s history).
