Lagos - Nigerian opposition candidate Atiku Abubakar on Friday called President Muhammadu Buhari's suspension of the country's top judge "an act of dictatorship", just weeks from elections.
Abubakar, of the Peoples Democratic Party, said the decision was a "brazen dictatorial act" and "the latest action in the ongoing rape of our nation's hard-earned democracy".
Buhari earlier announced that Chief Justice Walter Onnoghen would be suspended pending the conclusion of a trial on charges of failing to declare foreign currency bank accounts.
The president's opponents have accused him of trying to manipulate the judiciary, which would rule on any dispute in the forthcoming elections on February 16.
Abubakar, who is seen as Buhari's main challenger, has previously accused the ruling All Progressives Congress of trying to rig the result.
