Whitworth contested Stafford in 1768 on his own interest against Lord Chetwynd, the representative of the most powerful family interest in the borough, and Hugo Meynell, who was supported by Lord Gower. In a letter to Lord Grosvenor of 6 Jan. 1768
My men continue very steady and I increase very greatly, everyone says I am sure to be first upon the poll, notwithstanding the high price my opponents give I have greatly the majority ... Many people wonder how I dare attack two such powerful men. I did at first wonder at it myself but my success has made me forget those thoughts ... I have carried the whole on at my own expense and paid my way, and I think about £900 or £1,000 will settle me there for life.
The day of election, 18 Mar. 1768, Whitworth had a majority of 15 over Chetwynd and 31 over Meynell on a poll of nearly 400.
At first he voted with the Opposition: attended the Opposition dinners at the Thatched House Tavern in 1769 and 1770; and was one of the 26 Members who are known to have voted for Sawbridge’s motion for shorter Parliaments, 4 Mar. 1772. In the Parliament of 1768 he is recorded as having made over 100 interventions in debate, most of them between 1768 and 1771. He seems to have had little contact with either of the main Opposition parties.
Under date 16 Mar. 1772 Horace Walpole wrote of the debate on the committee stage of the royal marriage bill:
In Robinson’s list of September 1774 Whitworth was classed as a Government supporter, and it seems probable that he had Gower’s support at the general election when he was returned for Stafford unopposed.
His name first appears in Robinson’s secret service accounts under date 16 Feb. 1779: ‘Mr. Richard Whitworth in advance, £100’; next on 5 July 1779: ‘in full for one year, £200’.
Whitworth is not known to have stood again after 1780. He died September 1811, aged 77.
