Jacqui Smith may well have informed the relevant parliamentary authorities about her living arrangements and I am sure she does have a letter telling her that her arrangements conform to the letter of the rules. However, does she really think her arrangements fit the spirit of the law ?
If we asked 100 people on the street the simple question, which of these is the person's main home ?
a) The house they own. The house where their spouse and children live. The house where the children go to school from.
b) Their sister's spare bedroom where they spend a few nights a week.
How many people would answer (b) ?
I think we all know the answer.
