African leaders have been arriving in Addis Ababa to mark the 50th anniversary of the organisation which became the African Union.

While the bloc's principles stipulate respect for the rule of law, human rights and democracy, many criticise it for its failure to stop regional conflicts and its support for controversial leaders.

Amid the celebrations of union this week, the group will also have to take note of its failures to plan for a better future.
