The model was the Swedish idea of an "ombudsman". The corresponding Indian word "Lokpal" was, according to Arun Jaitley, coined during a debate on April 3rd, 1963, by an independent MP (who, much later, joined the BJP, and also had a distinguished ambassadorial record). The MP's son is now in the Congress, and as history would have it, is playing a key role in the current Lokpal formulation.
Who are this father and son?
