Conservatism
According to Alan Ware, Belgium, Denmark, Finland, France, Greece, Iceland, Luxembourg, Netherlands, Norway, Sweden, Switzerland and the United Kingdom retained viable conservative parties into the 1980s. Ware said that Australia, Germany, Israel, Italy, Japan, Malta, New Zealand, Spain and the United States had no conservative parties, although they had either Christian democrats or liberals as major right-wing parties. Canada, Ireland and Portugal had right-wing political parties that defied categorization: the Progressive Conservative Party of Canada; Fianna Fáil, Fine Gael and Progressive Democrats in Ireland; and the Social Democratic Party of Portugal. Since then, the Swiss People's Party has moved to the extreme right and is no longer considered to be conservative.
Open–closed political spectrum
Opposition to immigration is one of the starkest divides between open and closed parties. The closed position supports restrictions on migration, and prefers that immigrants integrate into the national culture. By contrast, the open position takes a more liberal stance on migration, and tolerates or even celebrates multiculturalism. Both left-wing and right-wing parties can be closed on the topic of immigration: the conservative Polish Law and Justice accuses immigrants of undermining Polish values and bringing in terrorists, while the socialist German Left Party considers immigrants a drain on the welfare state. Conversely, in the United Kingdom for example the Adam Smith Institute (a neoliberal right-wing organisation) and Vince Cable (a left-wing social democrat and former business secretary) stand together as some of the strongest defenders of immigration.
