Nigeria's ruling party candidate Bola Tinubu has been declared the winner of the African nation's disputed presidential election.

Nigeria's opposition parties have already contested the result, calling for a rerun of the election, citing violence and rigging that allegedly took place during Saturday's polling.

Mr Tinubu, a former governor of Lagos state and member of the ruling All Progressives Congress party, received 37 per cent of the vote, according to the electoral commission.
