The Bayelsa State Governorship Election Petition Tribunal has voided the election of Duoye Diri as governor of Bayelsa State.
The tribunal nullified the election on Monday based on a petition by the Advanced Nigeria Democratic Party, which argued that it was unlawfully excluded from participating in the election.
It also ordered the Independent National Electoral Commission (INEC) to conduct a bye-election within 90 days.
The ruling comes two days after same tribunal had dismissed three other petitions against the election of Diri and his deputy Lawrence Ewhrudjakpo.
