Swiss television on Sunday projections based on ballot results show Switzerland's voters have approved move to ban the construction of minarets, which right-wing parties have labeled as symbols of militant Islam.
The projections contracted by state-owned television DRS showed the Swiss swung massively in recent days from 37 percent support in pre-vote polls to 59 percent in the actual voting.
Claude Longchamp, leader of the widely respected gfs.bern polling institute, says the projection also forecasts approval by more than half the country's 26 cantons, meaning it will become a constitutional amendment.
The initiative was led by the nationalist Swiss People's Party, the country's largest.
Projections were based on actual voting returns.
