French President Emmanuel Macron has opened a discussion on extending France's nuclear deterrent to cover other parts of Europe. Initial talks involve a group of eight countries, including Sweden.
Finland, however, is not currently part of the group. Finnish law is one obstacle on this front.
Unlike Finland, where legislation explicitly restricts nuclear munitions, Sweden has no equivalent legal prohibition on the powerful weapons being present on its territory.
However, according to information obtained by Yle, there appears to be some desire within the cabinet to reconsider Finland's existing restrictions.
The Finnish government is preparing to overhaul the country's nuclear energy legislation, which currently includes a prohibition on the transit of nuclear weapons. The draft reform is under review at the defence ministry, and a government bill may reach parliament as early as next week.
A planned revision of the nuclear energy law would not address nuclear weapons. Instead, the issue is expected to be handled through a separate process.
Finnish law prohibits nuclear explosives in all forms. The import, manufacture, possession and detonation of nuclear munitions within the country are all explicitly banned.
The government has also sought to emphasise that the country has no intention of becoming a nuclear armed state.
Since joining Nato, Finland has twice supported Nato nuclear exercises with its F/A-18 Hornet jets in auxiliary roles.
Watch a commander of a F-35A squadron in the Dutch Air Force share his perspective on transporting nuclear arms and how he feels about performing such duties.
