Following the elections, the results in the Tessaoua and Zinder constituencies, where Sawaba had won all their seats, were annulled due to irregularities. The Tessaoua seats were awarded to the UCFA, whilst a by-election was scheduled for Zinder on 27 June 1959. Ballot papers were only printed for the PPN-RDA, and due to fears of violence, Sawaba did not put up candidates, calling for a boycott instead.[2] Following the by-elections, the UCFA controlled all 60 seats.
