A report published by Policy Exchange has called for Oxfordshire to be expanded, according to the Oxford Times.
Oxford would have a population of one million people, more than either Birmingham or Glasgow.
Cambridge and London would each recieve an extra million homes.
One wonders if Dr Leunig and Dr Hartwich, two of the report's authors have actually been to Oxford recently, although it appears that James Swaffield, their co-author, studied geography at Oxford University until 2004.
The infrastructure of Oxford already needs improving, with two expensive local bus services (£2 for a single from the centre of Oxford to Kidlington)and badly maintained roads.
No doubt many of these new residents will want to travel into Oxford to shop at weekends.
With hordes of tourists bumping people with garish rucksacks already clogging up the narrow streets of Central Oxford, can we really fit more people into the city centre on weekends?
Go to Broad Street on a Saturday afternoon. It's a seething throng of people.
The Green Belt is intended to prevent the South of England becoming some giant conurbation where children think grass is something you put in spliffs.
I have no objection to a re-examination of how large the Green Belt should be. Building some decent new towns with proper infrastructure and some character may be essential giving the rise in population.
What I do object to is this desire to build a million homes around Oxford. Will this mean that farmland will have to be purchased and farms demolished in order to build these homes?
Policy Exchange think suburbs a high qualiy of life. While housing may be cheaper, too many suburbs are dull places with little for children to do, leading to vandalism and intimidation.
The report, which you can read on the Policy Exchange website, seems to think there is no hope for Northern areas blighted by post-1984 decay and that people should move south.
Better public transport, in particular improved rail travel, and the promotion of Megabus for travel between cities would reverse this.
The BBC's move of some jobs to Salford may help, although we will only see in 2010.
If we have to have these wretched Olympic Games, maybe it would have been better to have had more events in the North and direct people to airports there.
The last thing London needs is house prices being pushed up further, especially in the East End.
No doubt Policy Exchange would have preferred us to hold the Olympics in Oxford, making full use of the Unversity Parks.
As for a million new homes in London, the Tube is already in need of constant repair work. Every weekend two or three lines are partially closed and the line I live on, the Metropolitan Line, is in need of an overhaul.
Crossrail may take some of the strain but unless we build some new London Overground lines (and we need much more coverage in South London), I cannot see how this would work.
David Cameron is distancing the Tory Party from this report. I cannot blame him.
