So would I growstuff.
I’ve written about the tax side. HMRC are not going to be interested. It isn't a police matter.
Re the electoral side - I don’t undertand what wrongdoing is being alleged.
The General Election of 2015 was the only one held under the rules of the Fixed-Term Parliament Act 2011.
Rayner was selected as the Labour Party's prospective parliamentary candidate for Ashton-under-Lyne in September 2014.
The Fixed-term Parliament Act 2011 led to the dissolution of Parliament on 30 March 2015 and the scheduling of the election on 7 May 2015.
Rayner sold her house on 17 March 2015.
The deadline for submission of election nomination forms is 19 working days before the election which would have been the 10 April 2015.
The candidate’s address does not have to be on the ballot, nor does not have to be in the constituency in which the person intends to stand.
As already explained, for voting purposes in Parliamentary elections, the Electoral Commission says:
If you split your time between two homes, you may be able to register to vote at both addresses. For example, you might own two properties and split your time between them, or you might spend time at different family addresses.
You can only vote in one constituency in a General Election or referendum but you can vote in more than one council election if properties are in different wards.
It’s entirely plausible for Rayner to have been registered to vote at one address (her owned property which she was perfectly entitled to do if she spent time there) and to have put another address on her election nomination forms which, in all probability, were completed after the sale of her house.
