Lord Cornwallis formed a high opinion of Robinson’s ability and industry during his first period as governor-general of Bengal. According to Hickey, it was with ‘a very independent fortune’ that Robinson went to England in 1802; but in January 1805 Cornwallis, having been reappointed governor-general, ‘understood that he is pinched in his circumstances’ and therefore asked Robinson, ‘in every respect the fittest person’, to accompany him as private secretary, even though he was ‘attached to his family’, had ‘other views’ and perhaps ‘would not willingly return to India’. Robinson accepted the appointment, but he left India for good after Cornwallis’s death there later in the year.
He benefited from a family friendship with Canning, who in 1807 recommended him to his fellow ministers for the next vacancy in the court of directors of the East India Company.
He was listed among Members expected to support government, but Rose told Arbuthnot, 8 Nov. 1812, of his suspicion that Robinson was ‘attached to Mr Canning’.
Robinson may have been left in political limbo by Canning’s formal dissolution of his party in July 1813, for in December it was reported, apropos of Honiton, that he had ‘become indifferent to the seat and to the party, and would resign the seat immediately, on being reimbursed the expenses of his election’.
Robinson retired from Parliament at the dissolution of 1818. In 1821 he was described as Canning’s ‘instrument’ at East India house and two years later he applied successfully to Lord Liverpool for a baronetcy.
