Historical UK By-Elections Discussion Thread

[Krago]

Does anyone know where I can find detailed maps of British parliamentary constituencies?  I am looking for a British equivalent of this:  http://www.govtrack.us/congress/findyourreps.xpd

Thanks for your help.

I had found the Ordnance Survey Election Maps site before, but:

(a)  the map viewer area is small,
(b)  there is no link to show entire Westminster constituencies on the map,
(c)  the Overview map is incredibly crowded with detail,
(d)  when you drag the map, it disappears and takes a few seconds to refresh, and
(e)  for some bizarre reason, you cannot zoom out very far - for the one I selected (Cities of London and Westminster Boro Const), you can't even see all of Hyde Park, let alone the whole constituency!

Do these boundaries exist in a GIS format?  Cannot some map keener on either side of The Pond overlay them onto Google Maps, like the American one?

Thank you so much, Your Grace!  (How do you address the Chancellor of a Duchy?)

Your advice was great.  I downloaded the Westminster constituencies file from the OS Boundary Line website, and created my own Google Maps overlay.  Here's my link to a map of the constituencies in Greater London:

I don't know enough kml code to get it all gussied up.  And when I tried to load all the constituencies in Britain, Google Earth just laughed at me.
