British Prime Minister Theresa May is in Nigeria, on her second leg of an Africa trip. She's signed bilateral agreements with the Nigerian president covering defense and trade. The visit is part of Theresa May's post-Brexit plan to reposition the UK as Africa's leading trading partner among G7 countries. Kelechi Emekalam has more.

Theresa May, setting foot in Nigeria for the first time. The British Prime Minister arrived here from South Africa, where she promised to increase UK direct investments in the continent by more than five billion dollars. Nigeria is Africa's biggest economy and also its most populous nation. Potentially the biggest market for British goods and services. May held closed-door meetings with President Muhammadu Buhari and signed bilateral agreements on defense and trade.

GEOFFREY ONYEAMA NIGERIAN FOREIGN AFFAIRS MINISTER "The UK already has a strong presence already in the oil industry but we would like to see more in manufacturing sector, for them to invest, because they get a lot of raw materials from Nigeria, if they were also developing manufacturing capacity in Nigeria to be able to add value to the raw materials, I think that is an area where they could make a difference."

Trade volume between Nigeria and the UK is estimated at about 4 billion dollars and Theresa May is looking to double that over the next decade. Besides trade, Britain has also been helping Nigeria with its fight against Boko Haram. The Islamist militant group has killed tens of thousands and displaced millions in the northeastern part of Nigeria in recent years. Under terms of the defense and security agreement reached here, Britain is expected to scale up its anti-terrorist training of Nigerian troops and supply them with added specialist equipment.
