 In January 1926, Nagy and István Sinkovics established the Kaposvár office of the Socialist Workers’ Party of Hungary (MSZMP), a semi-communist left-wing splinter group from the MSZDP.Nagy was successful in gaining 700 voters for the MSZMP Kaposvár parliamentary candidate, one of the party's few successes in the countryside west of Budapest.By this time Nagy had begun to prioritize his interest in agriculture over political leadership and rejected an offer from communist cadres from Vienna to build up the illegal KMP in western Hungary.
