Sir David – a long-standing critic of the island’s political system – offered £1 million for the feudal lease and title and a further £1 million compensation to the head of Sark, Seigneur Michael Beaumont, for the loss of his £28,000 a year salary.
But the offer, made in writing in January last year, was rejected.
In the letter, Sir David stressed that he had no interest in the feudal rights attached to the title and argued that the move would improve democracy in the island.
