Hi LB, looks as though we're the only late birds tonight ...
Ignoring the actual character involved, I would agree in principle that the head of Unite at 1,000,000 members is worth more than £100k pa, but Cameron as PM is only paid a basic of £142k - and he's supposedly in charge of >50m of us.
We don't however know what other 'additional' income might be coming in, I would imagine that the PM's position pays a hefty pension and leaving present to recover to normal MP status, I seem to remember that MP's losing their seat, are/were entitled to £60k +. Thank God for the milk round did I hear someone say!!
