Swiss voters were projected to approve by a slim majority a far-right proposal to ban facial coverings in a binding referendum on Sunday viewed as a test of attitudes toward Muslims.
Projections for broadcaster SRF, based on partial results, showed the measure passing 51% to 49%, with a two-point margin for error.
The proposal under the Swiss system of direct democracy does not mention Islam directly and also aims to stop violent street protesters from wearing masks, yet local politicians, media and campaigners have dubbed it the burqa ban.
