A Swiss citizens' initiative for accession to the UN Nuclear Weapons Ban Treaty has successfully collected the necessary signatures. The Federal Chancellery confirmed on February 17, 2026, that of nearly 107,000 submitted signatures, over 99 percent are valid. This obligates Swiss authorities to bring the initiative to a vote and thus submit a central question of Swiss security policy to the population.

Detailed Summary

The initiative submitted on December 23, 2025, aims at Switzerland's accession to the international treaty on the prohibition of nuclear weapons. With a validation rate of 98.8 percent (105,674 valid signatures out of 106,676 submitted), the initiative demonstrates broad support among the population. The high validity rate indicates organized and careful signature collection.

The initiative will now be transferred to the voting process. This means that the Swiss sovereign will directly decide whether Switzerland should accede to the UN Nuclear Weapons Ban Treaty – a decision with significant foreign policy and security policy consequences. The vote is expected to take place in the coming months.
