It is worrying to see that one of the country's largest regeneration schemes is being hampered by short term cash shortages.   Of course everyone recognises that the public purse still isn't exactly overflowing - but in terms of meeting housing need, regenerating brownfield land and protecting (if it needs protecting) the green belt, Old Oak and Park Royal ticks the boxes.  Yes, in terms of HS2 it still has an alarming uncertainty, but for private sector investors who are prepared to address that risk this could perhaps now be a great opportunity.
