The MPR elected its president every seven years at its national convention (five years before 1978). At that time, the MPR's president was automatically nominated as the sole candidate for a seven-year term as president of the republic; he was confirmed in office by a national referendum. Mobutu was elected unopposed as president three times under this system, with official figures showing an implausible 98 percent or more of voters approving his candidacy against at most 1.8 percent either voting "no," casting blank ballots or spoiling their ballot papers. Every five years, a single list of MPR candidates was returned to the legislature, with unanimous or near-unanimous support. All of these candidates were effectively handpicked by Mobutu.
