Once again, I will start to answer and then ask Mr. Le Goff to add more information.
When it comes to PPPs, I think that what we should learn from this situation is the importance of carrying out a comprehensive analysis using hypotheses based on the right information, an analysis that includes all the available information in order to decide whether a PPP is the best way to carry out such a project.
So I have no opinion on whether it is better to use a PPP or another option to build infrastructure. However, it is very important to carry out a proper analysis.
I will ask Mr. Le Goff to also answer.
