Nigeria election: PDP official protests over results

There have been chaotic scenes at the main vote counting centre for the Nigerian elections in the capital, Abuja.

The representative of the governing PDP, Elder Orubebe, interrupted the announcement of results, accusing the electoral commission of bias.

The head of the BBC Hausa service, who is at the collation centre in the capital Abuja, says the protest shows the PDP - the party of the incumbent Goodluck Jonathan - is losing the battle.
