The free movement of people is a key principle of the European Union, but it is being tested to the limit by the migrant crisis and the U.K's referendum on its future in the 28-country bloc. Meanwhile Africa is taking steps to establish the freedom of movement on its own continent.
The African Union (which consists of 54 African countries and was launched in 2002) announced this month that it planned to launch an electronic passport scheme in July. The electronic passport will facilitate visa-free travel among all the countries of the African Union.
Initially, only heads of state, government ministers and representatives of African Union will receive the passport. However, the intention is that each member state will be motivated to implement the laws and procedures required for visa-free travel and later issue an African passport to citizens.
The African Union aims for visa-free travel for all African citizens within the continent by 2020.
