According to Nigel Lawson, he as Chancellor wanted to introduce a transferable tax allowance between married couples, not the cursory £750 giving you a pound or so a week that Cameron is talking about, but the full allowance transferred. He said "Margaret would not let him, because she thought women who stayed at home with the children lacked gumption".
Basically Thatcher thought all women should aspire to be like her, and therefore major tax policy was crafted because of this!!!!
I was
when I heard him say this!!!!
