Swiss intelligence is warning of a targeted Russian campaign to influence the 27 September neutrality vote.
State broadcaster Russia Today has published an article claiming Switzerland had forgotten Russia's role in the country's creation — a framing the Bern historian Marco Jorio dismisses as abusive exaggeration.
The federal intelligence service says Moscow is combining diplomatic interference, factual errors and outright propaganda.
The initiative would enshrine strict neutrality in the constitution and is one of the year's most-watched federal votes. It is now less than seven weeks away.
The government is recommending voters reject the initiative.
