Five Reasons Why President Goodluck Ebele Jonathan Lost- BBC

Nigerians are so used to the idea that an incumbent should win presidential elections that President Goodluck Jonathan's failure to beat Gen Muhammadu Buhari needs some explaining. Here are five reasons why the opposition won:

1: Harder to rig
Past elections have been marred by serious irregularities and suspicions of rigging. In 2007 observers said the presidential poll was not "credible". In 2011 the vote was considered to be better run but observers said that rigging and fraud still took place.
This time the electoral commission took more steps to prevent rigging, including new biometric voters cards.
Also President Jonathan's party, the People's Democratic Party (PDP), had lost control of some key states which meant it could not control the electoral process there.

2: Boko Haram and security

The Nigerian army has made some recent gains against Boko Haram, but not enough to convince Nigerians
The election took place against the background of an Islamist insurgency in the north-east of the country. The Boko Haram militant group has killed 20,000 people and forced some three million others from their homes and President Jonathan was criticised for not getting to grips with this.
The poll was delayed for six weeks to give time for the security situation to improve, but even though most areas controlled by Boko Haram were recaptured, it seems to have come too late for many people.
