I already have a problem and I'm only looking at one 'Town Council' which is 
'Evesham CP' and has 5 wards in the OS data, but I'm looking for SIX for which 
town councillors are elected :)

I'm getting into QGIS and can see there have been no changes since 2010 but my 
next step is to get data I can view from JOSM and check against the 'list of 
streets' that are currently displayed on the Town Council website. AH ... as I 
suspected 'Evesham North' in the data consists of two wards on the ground, and 
it looks like a few other wards have the same problem ...

The ONS data set matches OS data, so I'll check with my contacts tomorrow on how 
we identify the smaller areas. I've got a complete database of the ONS dataset 
as part of my NLPG handling package, and I'd prefer to stick with the names from 
that over the ones in the OS data! But obviously there are a few extra 'tags' I 
can add from the OS data.

Looking at the 'raw vectors' I have in my mind something that I considered three 
years ago but never got around to because I did not have the tools. The bulk of 
the boundaries are the same 'layer to layer', so would it not make sense to 
extract a single clean set of ways from the data and then create relations that 
simply pick up the relevant ways and add the right tags. Combining the ONS data 
with the OS Boundary Line stuff? OK some of this stuff has been added, but only 
the county boundaries cover the whole of England, and Scotland and Wales would 
benefit from finishing that?
