NIGERIA A tale of two cities 7th September 2007 Amid growing mayhem in the Niger Delta President Yar'Adua has started to restructure the country's oil business It has been the worst of times in the oil capital of Port Harcourt in the 100 days since President Umaru Musa Yar'Adua was elected. And it has been the most uncertain of times in Abuja, the political capital. More than 70 people have been killed in clashes around Port Harcourt in what appears to be both a test of the new government's resolve and a settling of scores between rival political godfathers and their armed bands. In Abuja, politicians are still struggling to understand the new President's policy agenda and working methods. His understated approach and constant references to the rule of law could hardly be more different from the style of his rumbustious predecessor, Olusegun Obasanjo.
