Tens of thousands of people are attending the national convention of the All Progressives Congress, Nigeria's biggest opposition party, in Abuja.

Supporters, meeting on Friday, hope to defeat President Goodluck Jonathan and the People's Democratic Party when elections are held in February.

Gathering to elect a new leader, they say the ruling party has failed to tackle the Boko Haram crisis, poverty, corruption and unemployment.
