 Attempts to create a coalition of Hungarian opposition parties with the largest Slovak opposition party – Hlinka's Slovak People's Party (HSĽS) – were unsuccessful due to fear of Hungarian revisionist policy and potential discredit after the affair of Vojtech Tuka who was uncovered as a Hungarian spy.In 1936, both "negativist" parties united as the United Hungarian Party (EMP) under direct pressure of the Hungarian government and threat of an end to financial support.The party became dominant in 1938 and received more than 80% of Hungarian votes.
