My Dad's Diary : Wed 8th January 1947

"LAND BILL PASSED.

Mother called at night."

Again, I'm unsure of the reference here, but it may have been the Town and Country Planning Act 1947 which the Labour Government introduced to establish that planning permission was required for land development; ownership alone no longer conferred the right to develop the land. 

You'll begin to realise that my Dad and his Mother were very close.
