I am not a Labour (or Tory) voter but nor am I daft enough to imagine that MPs of any party are all knowledgable about areas such as tax law. Even Accountants (of which I am one) have areas of knowledge which are not in their everyday repetoire - and as they say "a bit of knowledge is a dangerous thing".
However, I would think and believe that a legal adviser, advising on the taxation (of which Stamp Duty is one area) of a property purchase would be well versed in such details, and if I consulted one regarding the tax due on a property purchase would be entitled to believe their statement that only the standard rate of Stamp Duty would apply in this case. In fact my DH and I have today had an appointment with a local solicitor to discuss our wills which may or may not involve the transfer of the assets of the spouse who dies first into a Discretionary Trust and would assume that her advice re taxes thereon is correct.
That advice may eventually prove to be incorrect, but that is not my first assumption.
We are all entitled to arrange our financial affairs in any legal manner which minimises the amount of tax payable. That is perfectly legal - indeed it is sensible. It is not only NOT Tax Evasion (which is basically lying) and not even Tax Avoidance (which is legal but employs little-known, devious and complex transactions that were never intended to provide people with a way of paying less tax. But selling a portion of the ownership of a property to the trust that supports the home of a disabled child is neither Evasion nor Avoidance.
Angela Rayner was perfectly entitled to do that and had sound personal reasons for doing so - and that transaction itself would presumably have no effect on the rate of stamp duty on a separate purchase of a new home.
Therefore I cannot see that she has done anything wrong, but my knowledge of Stamp Duty is not bang up to date and was never a part of my working experience as an Accountant.
Re council tax on her Ashton residence, if she lives there she pays council tax, unless regarded merely as a temporary visitor. I imagine she will also pay council tax on the new flat - but that isn't my area either.
Yes, the law re stamp duty on second homes is not straightforward but I have worked for several solicitors over my life who specialised in both trusts and property purchase who would have full and detailed knowledge of this area - and therefore would be trusted to advise correctly.
Leave the poor woman alone, FGS. Her "crime" (if any) is small fry compared to some of the millions of pounds of unpaid tax by some MPs who "forgot" to declare taxable transactions and still retained their jobs. And these were people with access to top lawyers and accountants, not relatively uneducated (though not stupid by a long chalk) young women who have seen life when it was really hard.
