The National Movement for Stability and Progress (Bulgarian: Национално движение за стабилност и възход, romanized: Natsionalno dvizhenie za stabilnost i vazhod, NDSV) is a liberal,[5][6] populist political party in Bulgaria.

Simeon served as prime minister until 2005 and the party remained part of the governing coalition until 2009, when they lost all their seats in the National Assembly.

NDSV was founded in April 2001, only 11 weeks ahead of a parliamentary election, after former Tsar Simeon II had announced his intention to become involved in the political life of Bulgaria.

One seat short of an absolute majority, it formed a coalition with the ethnic minority party Movement for Rights and Freedoms with Simeon Sakskoburggotski (his official name in Bulgarian since the end of monarchy) becoming prime minister.

[13] However, it was during Simeon's term that Bulgaria entered NATO and prepared the economic and political stability that was prerequisite for the country becoming a member of the European Union in 2007.

The party changed its name in June 2007, removing the name of the founder and leader and replacing it with "Stability and Progress", but retaining its Bulgarian acronym NDSV.
