Harvey was nominated by Henry Fox at Dunwich, for which place his brother Edward had been originally selected. On 17 Feb. 1761 Fox wrote to Fitzmaurice:
Harvey was a frequent speaker on a diversity of subjects. Horace Walpole thought that his speech against the war in Germany, 13 Nov. 1761, was ‘very sensible’;
Classed in Bute’s list of December 1761 as a follower of Fox, he appears in Fox’s list of Members favourable to the peace preliminaries, December 1762. He was present at the meeting at Sir Francis Dashwood’s, 25 Feb. 1763, of ‘60 or 70 persons, Tories and others’, met to give the King their opinion about troops in Ireland, and declared ‘that an augmentation in Ireland could not be made without an Act of Parliament’.
Harvey did not stand again for Dunwich in 1768, the interest there no longer being at the disposal of Government. He was nominated for Essex at a meeting of country gentlemen discontented with the sitting Members, but came bottom of the poll, with 1792 votes against 2035 for Jacob Houblon, the other unsuccessful candidate. He died 23 Oct. 1769.
