South Sudan declares independence

It’s the first week of official business for the world’s newest country. The Republic of South Sudan officially came into existence on Saturday, after gaining independence from the northern part of the country, still known as Sudan. It’s the first new country in the world since 1993. The BBC’s James Copnall joins us from Khartuom, in the north, tells us how this country came to be and what’s in store for its future.
