Background
Sir James was the son of Sir James Johnstone, 3rd Baronet and his wife Barabara, daughter of Alexander Murray, 4th Lord Elibank.
Sir James was the son of Sir James Johnstone, 3rd Baronet and his wife Barabara, daughter of Alexander Murray, 4th Lord Elibank.
He sat in the House of Commons of Great Britain for all but one of the years 1784 to 1794. They had no children. He joined the marines in 1748 as a Second Lieutenant, and rose to the rank of Lieutenant-Colonel in 1772.
Johnstone fist tried to enter Parliament at the 1774 general election, when he began canvassing Dumfries Burghs, where the interest of the 3rd Duke of Queensberry was dominant.
However, he made little progress and withdrew in favour of Alexander Fergusson of Craigdarroch, who was also unsuccessful. Queensberry"s candidate William Douglas took the seat.
Johnstone tried again at the 1784 general election. He took an independent line in Parliament, voting unpredictably.
He supported Parliamentary reform and abolition of the slave trade, opposed the penal laws, and protested the tax burden on the poor.
He supported the impeachment of Warren Hastings and of Elijah Impey, proclaiming in Impey"s case that: "We have beheaded a King, we have hanged a peer, we have shot an admiral, we are now trying a governor-general, and I can see no reason why we should not put on his trial a judge and a chief justice". His independence was less appreciated in Scotland, where he denounced the Scottish legal system, and twice opposed reform of Scottish seats despite petitions in favour of reform from the Dumfries Burghs. At the 1790 general election, he faced a strong challenge from Queensberry"s interest, who spent over £8,000, while Johnstone spent over £12,000 (equivalent to £128 million in 2016).
However Johnstone"s younger brother William had inherited a large fortune from his wife"s family.
He became one of the richest commoners in the empire and changed his name to William Pulteney. In 1790 he bought control of the four-seat borough of Weymouth and Melcombe Regis, adding to his interest in other boroughs.
To provide a seat for James, William asked Thomas Tyrwhitt Jones to vacate his seat at Weymouth, and at a by-election in 1791 James was returned in his place. He held the seat until his death, when William Pulteney succeeded to the baronetcy.
