A recent article from the BBC highlights once again issues dividing the U.K., but not simply in terms of the North-South divide:

London is producing goods and services worth £26,000 more per person than the per-head average of the North West, North East and Yorkshire regions. In absolute terms, this gap has almost doubled since 2001 (Charlie McCurdy, BBC news)

What the article suggests is that the problem is not individual productivity (how productive a worker is), but more about how the most productive sectors tend to be concentrated in the South of England, such as finance and technology.

At the same time, many other gaps are emerging.

The rural-urban gap has closed since the growth of jobs in urban areas since 2009. The regional gap however persists, more within than across U.K. regions.
