Over 50 million people in Nigeria, out of a population of about 180 million, have no access to electricity, Vice-President Yemi Osinbajo has said.

Speaking at the Financial Times Africa Summit in London yesterday, he said the government had embarked on measures to improve electricity access - including providing solar power to 20,000 homes in rural villages.

He added: "The opportunities in our power sector are immense, especially as we open the sector further."
