You said "What is an horrendously wealthy individual doing messing around as a wage earner? Could it be that being an MP or Minister conveys far greater advantage - contacts, info, contracts, nods, winks, consultancy fees, directorships, prestige and power etc etc ?"
If I misinterpreted that, then to quote the thread "I'm sorry".
Anyway, I'm also sorry that this thread is going on and on and on..
I am happy to leave the fate of the current sitting MP's to the democratic vote of the people, within the year....I am sure we will do the right thing.
