The new President of Sierra Leone, Julius Maada Bio, has said he will introduce free primary and secondary education for all children from September.

He told the opening session of parliament in Freetown that the education budget would be almost doubled.

President Bio said the money would come in part from spending cuts in other areas - and he would also seek funding from international donors.

Sierra Leone is one of the world's poorest countries, and more than half the population cannot read or write.
