Budget paper on city-regions

One of the associated Budget documents is a new paper on the economic importance of city-regions. I can't be arsed to read it, I'm afraid, but if anyone else does and feels like summarising it, please leave a comment. From the blurb:

As well as highlighting the importance of cities as drivers of economic growth and employment within regions, the document draws attention to the importance of the interaction between different strands of sub-national governance in maximising the economic potential of cities and regions.

Blah blah. Doesn't it sound boring?
