The only problem I have with Benn is that when he managed to change the constitution and make it possible to renounce a peerage, he made sure (or tolerated the insertion of a clause?) that future descendants of 'ex-peers' could redeem it. Young Hillary Benn is actually the third Viscount Stansgate if he cares to claim it. A bit like that bloke with the moat (whose father renounced his peerage) but is really the third Viscount Hailsham (should he want to be - and I bet he does.)
