It seems to be generally accepted that ex-Prime Ministers become extremely (in some cases obscenely) rich.
Not just Blair and Thatcher- John Major (from a very poor background) acquired a large holding in Carlyle Group after leaving office. How and why?
Ex-ministers should be required to declare and prove that all substantial receipts and capital holdings were not acquired as a result of actions (favours) carried out during their period of office.
Failure to do so should result in forfeiture of the funds to HM Treasury
Why does this idea matter?
Ministers should represent the citizens of the UK, NOT their own interests.
This simple provision would help to remind them of this before becoming involved with commercial contracts, wars, flu vaccination programmes… that mainly serve their own and/or their cronies' interests.
