Transparency International's 2011-2015 strategy recognizes that much more needs to be done to move beyond established policy circles and mobilize a broader range of citizens to take action against corruption. Social media tools will need to be harnessed by TI to reach and maintain meaningful engagement with these groups. However, the potential of social media also brings with it several challenges. This report , published by London School of Economics and Political Science elaborates on the analysis that led to the identification of ten distinct yet mutually reinforcing recommendations that support TI's efforts to employ social media and establish new networks of anti-corruption volunteers. The research conducted for this report seeks to build the knowledge base on the availability of social media tools that are used to engage citizens in the fight against corruption.
