Abstract
The corruption has spread among all the scenarios in the public sector; this universal behavior is being practiced from the simplest acts to even the most complex in the government. Public procurement has resulted extremely attractive to committing corrupt acts given the high amounts of money intended for that purpose, the effortless way to collect it and the high likelihood that such conduct becomes unpunished. Colombia and Spain are not exempt from this form of corruption and even though they have develop policies to cope with it a successful outcome has not been achieved yet, by the contrary, the level of public perception about corruption has increased, as exposed by Transparency International.
