UK Chancellor Gordon Brown began a week-long tour of Africa on January 12 with his aid project in serious jeopardy because of a failure to win American support. The Chancellor arrived in Nairobi at the beginning of a four-nation tour to promote his ambitious package of debt relief, aid and trade reform. His failure so far to win the backing of the United States threatens his goal of doubling global aid to $100 billion (£53 billion) under his International Finance Facility (IFF). Each of Mr Brown's visits has been carefully chosen to illustrate the benefits of his "Marshall plan", for example in Tanzania he will contrast the success of primary education, which has received a massive boost from debt relief, with healthcare, which is still in a parlous state.
