"People are right to be angry. Corruption threatens the well-being of our societies, the future of our children and the health of our planet. It must be fought by all, for all." These words by UN Secretary General António Guterres underline corruption as a serious obstacle to peace and sustainable development. Corruption weakens the level of trust within society and poses a threat to democracy. It also impedes economic development and erodes fundamental services such as healthcare, education and sanitation. People living in poverty and oppression are hardest hit by the harmful impact of corruption. Tackling corruption is thus a precondition for sustainable development and must be a vital part of international development cooperation.
