This is already the situation but what you are suggesting is not the solution.

First, it is unlikely that most people in Bromley and Bexley will want
to re-join Kent. Second, removing Bromley and Bexley will not change the
attitudes within the GLA or within County Hall.

The real solution is to scrap the office of Mayor Of London and to return
London to how it was before the Blair government inflicted this extra
layer of government upon us.

As there has been a huge change in attitude towards public transport
since 1997, most of the funding London has secured towards it in the past
decade or so would have been forthcoming anyway. Apart from public
transport, what real, incontrovertible benefits have come with a Mayor for
London?

Has either Mayor dealt effectively with the housing crisis? Has either Mayor
pursued policies likely to reduce air pollution? Has either Mayor devised a
strategy for creating employment for the large number of people who leave
school barely able to read, write and do basic arithmetic?

After the old GLC was abolished by Thatcher's government - in my opinion,
one of only two things that dreadful government got right: the other was
defeating Scargill - London was quite well run. I would love to go back to that
arrangement.
