In June 2018, the Swiss Government published an interdepartmental working group (IDAG) report on the implications of accession to the TPNW. 'At the current stage', the report concluded, 'the reasons against an accession of Switzerland outweigh the potential opportunities accompanying a signature and ratification of this treaty.' Both houses of the Swiss Parliament subsequently instructed the government to sign and ratify without delay. The Swiss Government plans to update the IDAG report and review its decision after the NPT Review Conference, now postponed to 2021, and contends that this fulfils the mandate given by Parliament. Parliament and NGOs disagree. In a letter to ICAN dated 20 July 2020, the President of the Swiss Confederation, Ms. Simonetta Sommaruga, wrote: 'As you will know, the Federal Council has discussed the Treaty on the Prohibition of Nuclear Weapons (TPNW) a number of times on the basis of an in-depth analysis by an interdepartmental working group. While the Federal Council decided not to join the Treaty at this stage, it took note of the position of the Swiss Parliament and agreed to re-evaluate the Swiss position on the TPNW earlier than originally planned. The outcomes of the next NPT Review Conference are one of several developments which will influence the Swiss re-evaluation.' Bern and Geneva have signed ICAN’s Cities Appeal.

- Switzerland should urgently sign and ratify the TPNW, and encourage other states to adhere to the Treaty.
