In August 2011 Tihipko and Prime Minister (and a Party of Regions leader) Mykola Azarov announced that Strong Ukraine and Party of Regions were going to team up and eventually Strong Ukraine would be merged into POR. Tihipko stated (in October 2011) he would become a Party of Regions member after the negotiations between the parties was concluded. The two parties merged on 17 March 2012. The same day Tihipko was unanimously elected Party of Regions deputy chairman and member of the Party of Regions political council. In the 2012 parliamentary election he was (re)-elected into parliament on the party list of Party of Regions. Tihipko did not return to a ministerial post after and hinted (in December 2012) that he would mainly deal with the ideology of Party of Regions since. He was one of the 36 members of the Party of regions faction (who consisted of 96 deputies) who voted in favour of the impeachment of President Viktor Yanukovych in February 2014.
