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.
Left–right political spectrum
A number of significant political movements—including feminism and regionalism—do not fit precisely into the left-right spectrum. Though nationalism is often regarded as a right-wing doctrine, many nationalists favor egalitarian distributions of resources. There are also "liberal nationalists". Populism is regarded as having both left-wing and right-wing manifestations (see left-wing populism and right-wing populism). Green politics is often regarded as a movement of the left, but in some ways the green movement is difficult to definitively categorize as left or right.
