In the 2015 parliamentary election held on 1 March 2015, the Reform Party received 27.7% of the vote and 30 seats in the Riigikogu. It went on to form a coalition with Social Democratic Party and Pro Patria and Res Publica Union. In November 2016, the coalition split due to internal struggle. After coalition talks, a new coalition was formed between Center Party, SDE and IRL, while Reform Party was left in the opposition for the first time since 1999. Rõivas subsequently stepped down as the chairman of the party.
