Why hasn't any one said anything before?

I found this article tonight. What I don't understand is why is it only now when the 2010 target for reducing the number of people in temporary accommodation is just around the corner, do the London Authorities raise this point? Surely it can't be because as many officers said when the target was announced that it was unrealistic and wouldn't be reached? Sorry to sound cynical but its amazing how senior management and councillors are unwilling to tell to tell central governement the truth
