For many years now I've been looking for the legal orders which defined the electoral division boundaries used in the 1995 Welsh local elections - the first elections to the current local government structure. They were not formally published as statutory instruments and all my web searches had come to naught. I found this a bit annoying as two of the orders (those for Blaenau Gwent and Neath Port Talbot) are still in force today.
Last week I had a breakthrough when I found ten of the orders in the Welsh Government's publications catalogue. On the offchance that they held copies of orders for the other twelve councils, I wrote a letter to the Welsh Government's freedom of information desk. It worked: in response the Welsh Government's archives have kindly supplied me with electronic copies of the remaining orders.
My impression was that in most councils the ward boundaries stayed the same as had been used previously
That's probably true in the case of Blaenau Gwent as it has almost the same boundaries as the 1974-96 district of Gwent, but it would be a lot more surprising in the case of Neath Port Talbot which came about as the result of a merger.
