Hmmmm. Letter to the Guardian.

For me this is an example of someone with a very specific London perspective on a London problem wanting to put their local sticky plaster on the whole country, and perhaps being deliberately provocative!
+I do not believe the "sitting on 600k Planning Permissions" comment - that is standard misinformation / sh*tstirring in the definition of "sitting on". 600k is a 3 year pipleline at current rates of approx 190k new dwellings per year for PPs that only last 3 years. There are many which are far further out on developments which will take perhaps a decade to build.
eg The Westminster Council Chelsea Barracks Planning Brief was dated 2006. Outline PP was 2011. Completion due 2018.

There are several more interesting letters on the page.
