France 2026 Municipal Elections
March 15, 2026 – March 22, 2026
France held thousands of municipal contests on 15 and 22 March 2026. The Ministry of the Interior reports first-round turnout of 57.1%. VIGINUM documented four foreign digital interference campaigns during the cycle, including Storm-1516, Rokh Solis and a seven-operation Storm-1679/Matryoshka cluster, while keeping measured reach separate from the existence of the operations.
Official results
This was not one nationwide candidate contest, so a national winner table would be misleading. The Ministry publishes results by commune and constituency. First-round turnout was 57.1%; second-round turnout was 57.03%, and 1,590 constituencies required a second round.
The Integrity Ledger
What the evidence establishes, and what it does not — side by side, each finding sourced and tiered.
What is established
- Foreign interferenceConfirmed
VIGINUM detected and characterised four foreign digital interference campaigns specifically targeting the 2026 municipal election period.
Sources:1 - Information operationsConfirmed
Storm-1516 targeted Paris mayoral candidate Pierre-Yves Bournazel with a false narrative laundered through a site imitating his campaign design and amplified by coordinated accounts.
Sources:1 - Information operationsConfirmed
Rokh Solis used fabricated sites and coordinated cross-platform relays to attack La France Insoumise and specific municipal candidates with false or misleading narratives.
Sources:1 - Information operationsConfirmed
VIGINUM imputed seven information operations targeting the municipal election to Storm-1679/Matryoshka. The cases used fabricated media and institutional reports to suggest the elections could not be held in good security conditions, and to allege vote manipulation — including claims about proxy-vote registrations among elderly and disabled voters.
More detail
The finding documents a repeated technique and attribution. It does not establish that the fabricated reports changed turnout, administration or the count.

What is not established
- Information operationsDebunked
Broad audience impact is not established: VIGINUM reported limited reach for the Bournazel operation and low online visibility for Rokh Solis.
- Result falsificationDebunked
The cited interference reports document manipulation of public debate, not alteration of ballots, counting or certified municipal results.
