However, a few countries in Europe (France, Spain, Sweden) and elsewhere (e.g. Argentina, Panama) do not use a single, integral ballot paper, but separate ballot papers for each candidate or party in the constituency. In Sweden, for instance, voters can pick up as many ballots for different parties as they wish, usually from a table in the polling station, and proceed to the voting booth. There, voters place the ballot paper of their preferred party in an anonymous envelope (and discard unused ones), before placing the envelope in the ballot box. If only the preferred ballot paper (and not a whole set of ballot papers), however, is picked up outside the voting booth from a table in plain view of voters and election officials, the secrecy of the vote can be at risk. Alternatively, ballot papers may be laid out inside the voting booth, such as in Spain. Nevertheless, whereas it is allowed that ballot papers are printed by political parties and also distributed outside the polling station, a large number of ballot papers may circulate throughout the country. Thus, such a model is particularly not recommendable for emerging and new democracies because it makes it more difficult to avoid open voting and, thus, vote buying.
