The huge economic boost that Africa could get from its burgeoning youth population "is close to being squandered", Sudanese billionaire Mo Ibrahim says following the publication of his foundation's latest report into African governance.

It has been publishing annual assessments since 2007.

Mr Ibrahim says "governance on our continent, on average, is slowly improving", but he has concerns about what will happen to the young people on the continent.

"Young citizens of Africa need hope, prospects and opportunities. Its leaders need to speed up job creation to sustain progress and stave off deterioration,” he says.

One of the statistics out of the hundreds produced is of particular concern.

The Mo Ibrahim Foundation says that education services have got worse in half of the countries on the continent over the past five years.
