Cissé had been Prime Minister of Niger under former coup leader Ibrahim Baré Maïnassara, who formed the RDP in 1997.
On September 12, Cissé founded the UDR-Tabbat, taking a number of supporters with him.
A joint list of the PNDS, UNI and UDR won two seats in the National Assembly.
After boycotting the 2009 parliamentary elections, Cissé and the UDR-Tabbat were prominent among the opposition coalition to President Tandja Mamadou's Sixth Republic of 2009–10.
Cissé ran for the presidency again in the 2016 elections, this time finishing ninth out of 15 candidates with 1.5% of the vote, whilst the party's parliamentary representation was reduced to two seats in the National Assembly after its vote share fell to 2.2%.
