This paper aims to examine and compare public sector structures involved in governance of Public-Private Partnerships (PPPs) in the UK and Spain and at the same time to assess the compatibility of the two national models' settings with the post-New Public Management framework shaped by the new paradigms/regimes. The spread and use of knowledge and skills capacities and the overall ability of the national institutional models to protect the public interest in an effective and efficient way is assessed together with openness and transparency of PPP programmes /progress in application of Public-Private-Citizen Collaboration (PC2) conception/ where the scale and quality of use of the Web 2.0 tools able to reach and engage citizens in the policy implementation process and procurement of individual schemes play an important role.
Special attention is paid to ways in which the private sector entities on the one side and citizens on the other can approach the public authorities and influence the features of a particular partnership and its results.
