The World Service is, and always has been, the jewel in the BBC's crown. Up until very recently (when the Government changed the funding arrangements) it didn't receive a single penny from the licence fee. (It was funded, indirectly, by the Foreign Office).
Despite the distorted picture painted by the dire Daily Wail, the BBC World Service Trust (which is at 'arm's length' from the BBC anyway) does a great deal of good:

The £800,000 from the BBC, quoted, by the Wail is misleading. The charity actually received £150,000 from the World Service (which, as indicated above, was actually money from the Foreign Office) plus £594,000 from the BBC Group (which includes, for example, the publishing and programme distribution sectors of the BBC - so it's not from licence fees).
Even if the £800,000 figure had been correct, what do you think that the BBC could do with it? It would only pay for roughly one episode of a costume drama (such as 'Cranford') or for about three quarters of one episode of a major 'buy in' from the USA (such as 'Glee).
