The primary political party in the United States associated with
the "right-wing" is the Republican Party. In the UK, The National
Front, is probably the most right wing of the political
parties.
In the United States, currently, the Republican party is the
most conservative or right-wing. It should be noted that there are
still some individual Republicans who would be considered moderate,
but most scholars (including conservative scholars) have noted that
the party as a whole has moved much more to the right in the past
several decades.
In many other countries, right-wing political parties can be a
factor in politics; for example in France, the National Front has
long been known for its harsh rhetoric and its strong
anti-immigrant stands. While sometimes, extreme right-wing parties
get some votes and provide an outlet for populist anger, such
parties generally lack the support of the majority of people,
appealing only to a small core group of followers.
