From huge infrastructure projects to supplying civil servants with paperclips, there is big money to be made from public sector contracts.
Evan Davis meets three business leaders with experience of bidding for - and securing - government contracts and finds out what it is like doing business with the state. How easy is it for smaller companies to get a slice of the public sector pie? And are we - the ultimate customers - really getting a good deal?
Evan's guests this week are; Uwe Krueger, CEO of Atkins, Jim Eyre, Director of Wilkinson-Eyre Architects and Giovanna Forte, Director of Forte Medical.
