/// I have read this, I know the area, and my brother in law has a house 2 streets away - he has just had his house valued and it is larger than this house and not worth £1.2. ///
An area can change dramatically 2 streets away.
Why do you want someone sacked for releasing these details, when you were perfectly happy to support Wikileaks founder Julian Assange?
Don't need the link, don't believe your question is irrelevant. The state should not be encouraging folk to have no control over their breeding and should not be in a £1.2M house at the ratepayers' expense. Difficult to know what to do, but being Lady Bountiful is not the role of the State. (Especially a State that allegedly is so poor it can't even afford to collect rubbish every week.)
I'd rather not have any large noisy family living next to me. Who's paying the bills is irrelevant. (In fact I think next door is council-owned, but they're all very quiet, so no problem.)
I've often wished for anyone other than the family of 5, including 3 noisy irritating boisterous brats, who live next door to us - but I'd rather stick with them, than the family in your question AOG - unless of course they are quiet!
