In the 2005 parliamentary elections on 4 July the party received 4% of the vote, winning four of the 118 seats in the National Assembly, whilst the CNDD–FDD won 64.[4] It had performed strongly in local elections in June in Bururi, Nyangoma's home province,[5] receiving 4.2% of the national vote and winning 135 of the 3,225 local council seats across the country.[6] It subsequently won a single seat in the indirect Senate elections on 29 July, which was elected by colleges of local councillors,[7] and gained an additional two co-opted seats.[8] However, Nyangoma went into exile the following year, before returning in 2007.
On 1 June 2010 the party was one of several that withdrew from the presidential elections scheduled for 28 June, accusing the Independent National Elections Commission of incompetence and a lack of impartiality.[9] Following the elections, Nyangoma went into exile again, fearing that his parliamentary immunity would be lifted.[9] The CNDD did not participate in the parliamentary elections on 23 July 2010.[10]
