Deborah Ross (http://comment.independent.co.uk/columnists_m_z/deborah_ross/article11294.ece) explains that:

Aside from anything else, we also plan to give South London away, because there is just no point to it

She also once wrote a fabulous piece of The Spectator, while reviewing a burger restaurant, about how she felt that south London should be demolished, so that she could extend north London into it. She then saw people waddling into the KFC over the road, and decided that they should be moved into south London before the demolition.

This is a plan with zero flaws, no?
