Unashamedly an exam question, hope that's ok with y'all!
A dies and leaves all her money to an IIP trust on death. Her husband is the life tenant.
The answer treats her as retaining her full NRB, so the husband can use it. Is that because gifting to an IIP where your spouse is the life tenant is akin to gifting to your spouse (so the transfer is exempt), or is it something else?
For the record, I got the rest of the question (and most of the others before it) right, I'm just struggling to understand this point.
