There is a rumbling effort by the council to have City Status granted to Medway. If they’d have kept their eye on the job back in 1997 it would never have been lost in the first place (at least for Rochester anyway).
Personally I like the nomenclature The Medway Towns and can’t see any benefit in having City Status. Seems rather like a bureaucratic anachronism to me.
Anyway The Medway Blogger post I’ve linked to above provides the clearest summary of the issues I’ve read so if you’re interested in this sort of thing I recommend you have a read.
