Campaigning has begun for what is expected to be Nigeria’s most expensive presidential election.
A record 79 candidates are in the race, including the incumbent President Muhammadu Buhari. But his hopes of re-election are threatened by criticism of his handling of the economy and the war against Boko Haram.
The Nigerian presidential election will be held in February 2019.
