Croydon is a borough but also a town. I'm just thinking of Croydon town itself. Not New Addington and all the rest of the bits. For sure Readings figure will cover Witley, Calcot, Caversham etc.. Just find it a bit odd it's not listed, it doesn't seem to fit anywhere. It's even in Surrey, but no one uses that either.
I was talking about Swindon.
Are you just reiterating your earlier Croydon comment?
