Stepney was returned for Monmouth on the interest of the Duke of Beaufort with whom he had been a close friend at Oxford. In Parliament he voted with Opposition on Wilkes, and on the Middlesex election (2, 3 Feb. 1769 and 25 Jan. 1770). He was classed as ‘pro, present’ in Robinson’s first survey on the royal marriage bill, March 1772, though as ‘doubtful, present’ in the second; and when he voted with Opposition on the naval captains’ petition, 9 Feb. 1773 and Grenville’s Election Act, 25 Feb. 1774, he was marked in the King’s list as normally a Government supporter. Nor does he appear in any of the minority lists between 1774 and June 1776, when he took up his appointment as envoy at Dresden.
On 1 Sept. 1776 Stepney, just over two months after his arrival at Dresden, wrote to his friend Sir Robert Murray Keith, minister at Vienna:
You are very good to interest yourself about my situation here;—it is hitherto as uninteresting to myself in all the agreements of society as it is possible to be ... I do not think it will improve by the arrival of greater numbers ... But perhaps the fault is in myself and the humour I arrived here in—no man on earth is more ready to look on that side for defects than I am.
In January 1778 he returned to England for six months’ leave. Back in Dresden, he wrote to Keith, 1 Dec.:
I have no news from England but what the newspapers bring, but am very impatient for the meeting of Parliament—have you any thoughts of attending this year? I am never without hopes till the winter is further advanced, though I scarce think I shall be summoned this time, and can’t possibly ask it so soon.
Add. 35510, f. 300; 35515, f. 117.
British visitors were a welcome diversion: Wraxall, who visited Dresden in 1778, noted that their visits were ‘rendered peculiarly agreeable’ by the ‘hospitality and polished manners’ of Stepney whom he described as ‘one of the finest gentlemen to have been employed on missions during the present reign’.
I do not know whether you are informed that I was removed to this court without any solicitation on my part, and that in some respects the removal was far from advantageous. I wrote, however, to Lord Grantham at the time, that I should not think of asking for additional appointments, unless I found after some months’ experience that it was impossible to go on without them. Still less shall I say anything on this head as yet to you. I shall delay the moment of entreating you to lay such a request before his Majesty as long as I possibly can.
If forced to do so, he would submit to Fox’s judgment in ‘disposing of me in any way you think proper’.
In 1784 Stepney seems to have thought of standing for Carmarthenshire,
Stepney does not seem to have attempted to re-enter Parliament. He appears to have spent his later years abroad, and was among the English imprisoned by Napoleon during the war with France. He died in Hungary 3 Oct. 1811.
