In 1760 Croftes’s parents began negotiating for a seat for him, and on 9 June he appears in Newcastle’s ‘list of persons to be brought into Parliament’, having been mentioned to him ‘by the Duke of Grafton, at the request of Mr. Croftes, and by Mr. Page at the request of Mrs. Croftes’.
In 1771, at the suggestion of Grafton, now chancellor of Cambridge University, Croftes vacated his seat at Downton to stand for the university. His nomination was not well received: ‘sending down so young a man, and so little known, has given much offence’, wrote the Bishop of Lincoln to Lord Hardwicke, 5 Feb. 1771;
We have no particular objections to him as a private man; nay we believe him equal to transacting the business of Downton, but we by no means think him of consequence enough in life to be the representative, or of ability sufficient to support the interest of the University of Cambridge.
Although an independent section of the university put up their own candidate, Croftes was returned by 76 votes against 45. His only recorded votes in this Parliament were on the royal marriage bill, March 1772, and on the naval captains’ petition, 9 Feb. 1773, when he was classed in the King’s list as a friend voting with Opposition.
After an unopposed return in 1774, his first recorded vote, on the civil list debts, 18 Apr. 1777, was with the Opposition, with whom he henceforth regularly voted. There is no record of his having spoken in the House.
In 1780 he was defeated at Cambridge University, and did not stand again for Parliament. He died 5 July 1783.
