 At St. Helena in July 1817 he alluded to him with calmness as ""habile"" and ""adroit"", but he always maintained that the accepted version of the celebrated interview of 13 March was ""plein des faussetés"".After his return, not occupying a seat in either house of parliament, Whitworth sank for ten years into comparative insignificance, but in 1813, owing to his wife's connection with Lord Liverpool, he was made on 2 March a Lord of the Bedchamber to George III, and on 3 June was appointed Lord Lieutenant of Ireland, in succession to the Duke of Richmond, a post which he held until October 1817.In the same month he was created an English peer as Viscount Whitworth, of Adbaston in the County of Stafford.
