The notion that public private partnerships are the most cost-effective mechanism is absurd. Everybody knows that PPPs are the most expensive option for the State. Sometimes there is no option but to have PPPs. However, the reason there are no other options in such cases is due to lack of investment and delay by the Government. Due to Government dithering over the Luas/metro, we will not, as Senator Wilson stated, see these services in my area of Dublin until 2015 or even later, and it is sad to boast about that.
