New constituency data

I got a question the other day about the electoral constituency data, specifically if I had the data for the new constituencies that will come into existence at the next General Election. The data on the site is from the ONS Postcode directory which is for the current constituencies. It seems the ONS update this kind of boundary data when it becomes active, i.e after an election, so I can't currently provide it from that source. But the ONS have recently released the data separately. If the postcode data for one of these new constituencies would be useful to you, let me know and I can produce a list of the postcodes for you. I'm unlikely to do it for all constituencies unless there's a big demand
