Osborn, who had regained his county seat in 1818 through the default of one of his opponents, stood again in 1820, heedless of his substantial election debts. He was alleged to have created the impression that if he was returned in 1818 he would resign his office at the admiralty; and his failure to do so lost him support, as did attacks on him in The Times, where he was denounced as a placeman whose professions of ‘independence’ were manifestly bogus and who had no right to occupy a county seat. Yet he bragged of his connection with a government which had defeated French tyranny and revolutionary doctrines. His two Whig opponents stood firm on this occasion and, despite the interference of government on his behalf and financial assistance from leading county Tories, he was beaten into third place amid public recriminations with the Whigs.
A year elapsed before government created an opening for him by providing Lord Galloway’s brother, who sat for his group of Scottish burghs, with a customs place. As ‘one of the treasury phalanx’, Osborn naturally voted unswervingly with his colleagues in office;
Osborn surrendered his office and seat in Parliament in return for a place in the audit office early in 1824 and remained there for the rest of his life. His salary was £1,200 a year but, with his large family and accumulated election debts, he had difficulty in making ends meet. In September 1842, harking back to his devoted support of Pitt some forty years earlier, he asked Sir Robert Peel to find a civil service place for his second son, who was proving too delicate for the army:
It would in a great measure relieve me from a great load of anxiety; and would indemnify me for a great deal of vexation I have suffered, and tend materially to the comfort of the few years that may remain to me.
Peel could not oblige him.
in consideration of my long standing in this office, and of having spent nearly fifty years in parliamentary and civil service ... If Lord Liverpool’s health had been spared for a very little longer time [in 1827] I should have received an appointment in addition to that which I now hold. But these are not days for pluralities.
Peel again dashed his hopes:
I must claim an unfettered right to make that selection for the appointment in question, which I may deem most advantageous for the efficient conduct of the business of the department and I cannot admit the claim which you urge for consideration in some other way in the event of your not succeeding Mr. Larpent ... The civil patronage of the government is so totally inadequate to meet even a small portion of the claims upon it that I cannot hope to have the pleasure of finding suitable employment for your son.

Osborn died in August 1848 and was succeeded in the baronetcy and family estates by his eldest son George Robert (1813-92).
