In my last blog post, I explained the new service TheyWorkForYou offers to show you what constituency you will be in at the next general election. Now I’m going to show you why you shouldn’t use anything else.
The defintions of the boundaries for the forthcoming constituencies in England were originally published in The Parliamentary Constituencies (England) Order 2007 (SI 2007/1681), based on ward boundaries as they were on 12th April 2005. However, due to some local government changes since that date, The Parliamentary Constituencies (England) (Amendment) Order 2009 (SI 2009/698) was published changing the boundaries for four constituencies – Daventry, South Northamptonshire, Wells, and Somerton & Frome – to be based on the new council wards as they were on 3rd May 2007.
The forthcoming constituencies in Northern Ireland were defined in The Parliamentary Constituencies (Northern Ireland) Order 2008 (SI 2008/1486). In this, Derryaghy ward was split between two constituencies – Belfast West is given “that part of Derryaghy ward lying to the north of the Derryaghy and Lagmore townland boundary.”
All of which means that other sites that try to tell you what constituency you will be in at the election invariably get it wrong.
Both Labour and the Conservatives say that BA6 8NJ is in Wells at the next election, when it will be in Somerton & Frome. Both say that NN12 8NF will be in Daventry, when it will be in South Northamptonshire. I assume that both sites are using boundary data predating the Amendment Order from March 2009. The Conservatives also say that BT17 0XD will be in Lagan Valley when it will be in Belfast West; Labour simply say “Northern Ireland” for any Northern Irish postcode you provide.
The Liberal Democrats site currently returns no results for any postcode, which I assume is a bug 🙂
TheyWorkForYou’s “constituency at the next election” service gives BA6 8NJ in Somerton & Frome, NN12 8NF in South Northamptonshire, and BT17 0XD in Belfast West. There is enough confusion with the changes to boundaries for everywhere except Scotland, that it is somewhat frustrating to have it compounded by sites giving incorrect information. The lack of any official service also doesn’t help.
