The poster, unveiled in railway stations on Monday, shows a woman wearing a burqa with the strapline “Uncontrolled naturalization? No to facilitated naturalization”.

It was commissioned by a committee co-led by Swiss People’s Party (SVP) MP Andreas Glarner to oppose the forthcoming referendum on facilitated naturalization for third generation immigrants, which goes to the polls on February 12th.

Opponents of the bill – which would make it easier for third generation immigrants born and bred in Switzerland to get a Swiss passport – feel it could allow foreigners who are not well integrated to become Swiss.

On launching the posters Glarner told the press that the burqa was a “symbol of lack of integration”

However earlier in the week some politicians lambasted the posters, saying the bill had nothing to do with burqas.

And it seems many members of the public agree.
