The Constitution of Ukraine foresees the removal of an elected representative from the parliament. According to its Article 81 paragraph 2 (6) and last paragraph1, as currently in force, an elected representative who, having been elected as a member of a political bloc, moves to another political formation within the lifetime of the legislature for which he or she was elected, loses his/her seat. The last paragraph of this Article gives the power to take such decision to political parties in the following terms:

“Where a People's Deputy of Ukraine, as having been elected from a political party (an electoral bloc of political parties), fails to join the parliamentary faction representing the same political party (the same electoral bloc of political parties) or exits from such a faction, the highest steering body of the respective political party (electoral bloc of political parties) shall decide to terminate early his or her authority on the basis of a law, with the termination taking effect on the date of such a decision”.
