This chapter reviews Botswana's integrity mechanisms within the business sector. It examines the role of the state owned businesses, by far the majority in Botswana,as well as the emerging privately owned business sector. It compares the role of various kinds of legislation relating to unlisted and listed companies, and the role of oversight bodies. In addition to relying on legislation and practice relating to business in Botswana, the authors of this chapter conducted an extensive survey of listed and unlisted companies, and conducted interviews with people in the business sector.
