The Swiss was expected to head to the polls Sunday to decide whether to ban almost all advertising of tobacco products and separately on a blanket ban on all animal testing.

In-person voting on those and other topics will begin at 10 am (0900 GMT) as part of Switzerland's direct democracy system, although most people vote in advance by post.

Recent polls indicate that the initiative to tighten Switzerland's notoriously lax tobacco laws by banning all advertising of the health-hazardous products wherever minors might see it - effectively all settings - is the most likely to pass.

Switzerland lags far behind most wealthy nations in restricting tobacco advertising - a situation widely blamed on hefty lobbying by some of the world's biggest tobacco companies headquartered in the country.

Currently, most tobacco advertising remains legal at a national level, except on television and radio, or ads that specifically target minors.

Some Swiss cantons have introduced stricter regional legislation and a new national law is pending, but campaigners gathered enough signatures to spur a vote toward a significantly tighter country-wide law.

Opponents of the initiative, which include the Swiss government and parliament, say it goes too far.

Philip Morris International (PMI), the world's largest tobacco company, which, like British American Tobacco and Japan Tobacco, is headquartered in Switzerland and which has helped fund the "No" campaign, described the initiative as "extreme."

"This is a slippery slope as far as individual freedom is concerned," a spokesman for PMI's Swiss section told AFP, warning that it "paves the way for further advertising bans on products such as alcohol or sugar."
