I'd do it now if I were you - because if Labour in their current guise are ever elected, anybody who has any money or property or who has the temerity to do reasonably well out of life, is going to be well and truly rogered.
The current Labour leadership hate the thought of inheritance, because in their twisted minds it's unearned income which should go to the state....hence the recently published paper by Chief Lefty Lunatic George Monbiot, but endorsed by the Labour leadership, of effectively lowering the threshold before inheritance tax kicks in to £125k (and I bet that stuck in their craw as they'd prefer a £0.00 threshold).
