Can't keep a good man down?

As an interesting addendum to Saturday's post, I had thought that when Tony Benn, then Viscount Stansgate, renounced his title, that the title would cease to exist.  But apparently the change in the law which allowed him to do this made it clear that such a revocation would be personal to the individual involved and would cease to have effect on that individual's death.  So the title survives and his eldest son has now become the new Viscount Stansgate.
