The Integrity Pact is a powerful tool developed by Transparency International to help governments, businesses and civil society fight corruption in public contracting. It consists of a process that includes an agreement between a government or government agency (‘the authority’) and all bidders for a public sector contract, setting out rights and obligations to the effect that neither side will pay, offer, demand or accept bribes; nor will bidders collude with competitors to obtain the contract, or bribe representatives of the authority while carrying it out. An independent monitor who oversees IP implementation and ensures all parties uphold their commitments under the IP brings transparency and invaluable oversight to all stakeholders in a contracting process. This manual is a hands-on, practical guide to familiarise government officials in charge of public procurement processes with the Integrity Pact and to provide them with tools and ideas for its application.
