Why do British charities want to shut down private schools in Africa?

Why would anyone who claims to care about the world’s poorest children try to shut down their schools? It’s strange and sad, but several British charities, in cahoots with some British unions, are making a concerted effort to close down hundreds of schools in Africa. They are doing this because they dislike private education, seeming not to care that this will destroy the life chances of thousands of desperate children, forcing them, at best, into state schools where the teachers are often absent, drunk or incapable.
