[12] Čižinský became a representative of the city district after 2014 municipal elections as leading candidate of the entity Praha 7 himself (e.g. KDU-ČSL and non-partisans).

[20] In the 2018 municipal elections, Čižinský received 80,552 preferential votes, the most number of all the candidates.

[22] Although he defended the mandate,[23] the candidate led by him finished fourth with a gain of 14.73%, thus reduced its representation.
