Nyon 2026 Elections.Results, Second Round and What's Next

On Sunday 8 March, Nyon residents voted to shape the city’s political landscape for the 2026–2031 legislature. Now that the results have been confirmed, including a late adjustment that shifted the balance in the council, we have a clearer picture of how the next five years will begin. But with no candidate elected to the Municipalité in the first round, the final outcome is still to come. Here’s what’s been decided, what’s still open, and what happens next.

Two Votes, Two Roles

In Nyon, voters were electing two separate bodies on the same day:

  • The Municipalité (executive committee) - the 7 people who run the city day to day

  • The Conseil communal - a 100-member council that debates and approves decisions

They work together, but they’re elected in two different ways.


What’s Been Decided and What Hasn’t

Voter turnout was just under 40%, which is fairly typical for local elections, but also a reminder that a relatively small portion of the population ultimately shapes the outcome.

  • The Conseil communal (council) which debates, questions, and votes on decisions, is now fully elected.

  • The Municipalité, which takes action and executes those decisions, is still undecided.



The Municipalité Is Still Open

Unlike the council, the Municipalité is elected using a majority vote system. Candidates don’t just need to come first, they need to secure more than 50% of the votes to be elected in the first round. In this election, several candidates came close:

  • Alexandre Démétriadès (PS) 48.41%

  • Pierre Wahlen (Les Vert·e·s) 46.69%

  • Olivier Riesen (PLR) 44.92%

But no one crossed that 50% threshold.


What happens when no one reaches 50%?

A second round is triggered. This is called a ballotage général, where:

  • All seats remain open

  • Candidates run again

  • The final 7 members of the Municipalité are decided


A second round of voting will take place on 29 March to determine who fills these 7 seats.


The results of the municipal election were announced at 4:30 p.m. by Ms. Muriel Cardinaux, President of the Municipal Council.

The Conseil Communal Final Results

This is where we do have a clear outcome. Based on the final count, the council is now slightly more centre-right leaning.



A Small Error… That Changed the Result


One important detail emerged after election day. Around 200 ballots were initially miscounted, which led to a correction in the final results.

The impact:

  • The PLR gained additional seats

  • The PS, Greens, and PIN each lost one seat

  • The PLR became the largest party in the council

A small administrative error, but one that shifted the political balance.


What Happens Next

All eyes now turn to the second round.

Sunday 29 March → Final vote for the Municipalité

This is the moment that will determine:

  • Who leads the city

  • How decisions are implemented

  • The overall political direction of Nyon


Because while the council sets the tone, the municipality drives the action. And with no clear winner in the first round, your vote still has a big role to play. These decisions will shape the everyday reality of living here from schools and infrastructure to culture, housing, and community life.
