Loftus, who served with the cavalry in the American war, offered to raise a regiment of light dragoons in 1793. The offer was accepted but he had to obtain a bounty from government to do it.
Loftus declined a compromise with St. Vincent, Addington’s first Lord of the Admiralty, at Yarmouth in 1802, even when St. Vincent offered him a seat free of expense.
Loftus was listed as a supporter of Pitt in September 1804 and July 1805. He voted against the censure of Melville, 8 Apr. 1805; but only two minor contributions of his to debate are known during Pitt’s second ministry. On 13 May 1806 he informed the House that he had voted for Pitt’s Additional Force Act in the hope that it would work; as it had not, he was now prepared to vote for its repeal, but he feared that Windham’s new plan was over-optimistic: bounties for recruits would not so readily be done away with, though some form of limited service, if not in wartime, was desirable. He went on to give his support to limited service, 30 May. On 3 July, moreover, supporting the training bill, his only complaint was that it did not go far enough to provide for an armed population. He thought naval supremacy was no security against a surprise landing by means of Dutch fishing boats. On 10 Mar. 1807 he was teller against a tactical delay of the engrossed bill to abolish the slave trade.
Loftus was clearly unsympathetic to the Grenville ministry’s plan for Catholic relief: he claimed (26 Mar. 1807) that their proposals went far beyond those contained in the Irish relief bill of 1793, which they claimed as a model, and were unnecessary since the great body of the Irish Catholics enjoyed the same advantages as the Protestants. He supported the Irish insurrection bill, 24 July 1807, and welcomed Henry Grattan’s unexpected speech in favour of it. He thought the militia transfer bill ‘highly expedient’, 5 Aug. It is very difficult to believe that he was in the minority critical of the Copenhagen expedition, 8 Feb. 1808, though so listed. He had recently received a governorship. His wife’s step-mother, Lady Townshend, said to be excessively partial to him, had asked the Duke of Portland to make him barrack master general if possible.
At the election of 1812 Loftus resumed his seat for Yarmouth on the Townshend interest. He was listed a Treasury supporter, but he was not such an active one in that Parliament. He voted against Catholic relief throughout in 1813 and again in 1816 and 1817. On 23 Feb. 181 6 he presented his constituents’ petition against the property tax, but he voted for its continuation, 18 Mar. He defended the record of the Guards during the debates on the army estimates, 11 Mar. 1816. No other speeches are known. On 24 Mar. 1816 he took a month’s leave for illness and no votes of his are known after 23 June 1817, when he supported the suspension of habeas corpus. He was defeated at Yarmouth in 1818 and nothing came of a report that he would contest the subsequent by-election:
