Csaba János Tóth (born 22 April 1960)[1] is a Hungarian engineer, entrepreneur and retired politician, a former member of the National Assembly.

[2] Tóth was a successful businessman in the 1990s, when he was primarily engaged in real estate investment, but his activity in this direction is rather vague, he does not detail this period in his autobiographies.

After the president of the local Roma minority self-government claimed that the Tóth had artificially increased their membership – the party organization had swelled from forty to five hundred in one night – and Tóth and his colleagues paid for their admissions, in order to strengthen the county branch on national level and its voting share within the party's national electoral board.

[4] Hiller also decided to dissolve and reorganize the entire Vas County branch in 2005,[3] entrusting Péter Kiss with the task.

[3] The corruption allegations against Tóth became a neuralgic point within the joint opposition alliance United for Hungary prior to the 2022 Hungarian parliamentary election.

The MSZP nominated him as their candidate in Zugló for the 2021 Hungarian opposition primary, also supported by the Democratic Coalition (DK) and Jobbik, in addition to Gergely Karácsony, the mayor of Budapest.

[6] Momentum leader András Fekete-Győr expressed his rejection of the candidacies of some MSZP politicians in the primary, such as Attila Mesterházy and Csaba Tóth.

Tóth cited the unfair attacks against him, but it is presumable that stepped back due to the leaked data which show Hadházy's crushing victory against him.

As a result, Ákos Hadházy became the joint opposition candidate and subsequently won Zugló constituency in the 2022 parliamentary election.
