Putting aside the entire case of hiring a tiler for $1.20 an hour, we learn Taito Phillip Field has also had his wife receiving money from taxpayer funds. Now how many rules does this break:
1) Strictly forbidden for MPs to hire spouses or children
2) The payments were in cash, so bang goes the tax laws
The e-mails make very clear that there was a deliberate attempt to flout the laws by not listing her on the payroll, but to have the money paid to another staff member who would then pay her.
What would be interesting to find out, is how long this has been going on for.
