Rainsford, an army officer, regarded a seat in Parliament as a means of assisting his promotion in the profession. In December 1788 he had given up his seat on the interest of his friend the 2nd Duke of Northumberland’s brother, Lord Lovaine having sided with Pitt over the Regency, while the duke went over to opposition. The duke made it up to him by returning him for his borough of Newport at the general election.
in full hopes of going down the remainder of the hill of life in comfort and ease under his own roof and enjoying the society of his family and friends, and by strictly observing his duty to God and his neighbour to go when called upon to that regime of eternity assigned to those it shall please God to approve of for that purpose.

To achieve tranquillity, Rainsford also divested himself of his seat in Parliament. Soon after his return, his patron the duke wrote, 5 May 1796,
In his reply, 7 May 1796, Rainsford informed the duke that he was not attending the House—‘was the duration of Parliament of any longer date than is expected I would have taken the same line of conduct as in 1789 [in fact December 1788] and begged leave to vacate my seat’. He declined a seat for the next Parliament, assuring the duke that this made no difference to their private friendship. The duke assured him that he had made the right decision.
