With regard to system design and route alignment, if we opt for PPP, we should allow as much discretion as possible to private sector bidders.

The metro saga has been running for a long period and decision time is approaching. We have received many reports, studies and evaluations. It is time now to decide whether we are going to proceed with this project.
