It is possible for 15 or more deputies to form a parliamentary faction (a lawmaker can join only one faction; the chairman and his two assistants cannot head factions of deputies).
A faction of nonpartisan deputies under the name Reforms for the Future existed between 16 February 2011 and 15 December 2012. A faction of nonpartisan deputies under the name For Peace and Stability existed between 2 July 2014 and 27 November 2014.
In 1998 - 2000 there was another parliamentary faction Labour Ukraine that existed without its political party until it was registered by the Ukrainian Ministry of Justice in June 2000.
The Communist Party of Ukraine (Soviet Union) was prohibited in 1991, however its members were not excluded from the Ukrainian parliament. They formed a parliamentary faction of the Socialist Party of Ukraine. For the 1994 parliamentary elections however the ban on communist parties was lifted and there were two parties with similar ideologies running for parliament the Socialist Party of Ukraine and the Communist Party of Ukraine that was reestablished in 1993.
Political alliances and blocs (1998–2012)
The idea of electoral blocs as a loose association of parties was introduced in 1998, however it did not become popular right away. The real success of electoral blocks came in 2002 when the Bloc of Victor Yushchenko "Our Ukraine" gained the most parliamentary seats. The electoral blocs system was liquidated in 2011 forcing registration of individual parties for the next 2012 parliamentary elections. The longest existing political blocs were Our Ukraine and Bloc of Yulia Tymoshenko.
The association of parties however was transformed into a new concept of an "umbrella party" when several parties temporarily unite under such party that becomes a core party of informal electoral bloc. Below is the list of official electoral blocs in 1998 - 2012 that led to creation of their own parliamentary factions.
Bloc of SPU-SelPU (1998–2002)
Our Ukraine (2002-2012; Bloc of Viktor Yushchenko, Our Ukraine-People's Self-Defense Bloc)
For United Ukraine (2002–2006)
Bloc of Yulia Tymoshenko (2002–2012)
Bloc of Volodymyr Lytvyn (2007–2012)
The following blocs did not form their parliamentary factions due to small number of their representatives.
Labor Ukraine Bloc
National Front (Ukraine)
Party of Labor (Ukraine) - Liberal Party of Ukraine
