The leaders of more than 40 African countries have signed a deal to create one of the world's largest free trade blocs, promising to bring prosperity to more than 1.2 billion people.

But some of the continent's biggest economies, including Nigeria and South Africa, have so far refused to join. And with more than 80% of African trade currently done outside the continent, what impact will the new deal actually have in Africa?

Some people on the streets of Kampala, Uganda, tell us they fear increased competition from neighbouring Kenya, and we ask Tonye Cole, billionaire co-founder of power and infrastructure giant Sahara Group, why his native Nigeria has decided not to take part.

Plus, we hear words of optimism from Ghana's trade minister, Alan Kyerematen, and Arancha Gonz谩lez, executive director of the International Trade Centre.
