On the death of the 1st Duke of Northumberland in 1786 his sons Hugh, the 2nd Duke, and Algernon, created Earl of Beverley in 1790, went separate political ways. Northumberland attached himself to the Prince of Wales, while Beverley supported Pitt. The duke wrote in 1811 that no ‘political intercourse of any kind’ had ‘subsisted since between Lord Beverley’s family or mine’.
He supported Pitt and, initially, Addington, at whose invitation he moved the address, 29 Oct. 1801, but he voted, along with his father-in-law, for inquiry into the Prince of Wales’s claims to duchy of Cornwall revenues, 31 Mar. 1802, having been appointed to the civil list committee on this subject, 17 Feb. He visited France after peace had been concluded and on his return followed Pitt’s political line, voting with him in the division of 3 June 1803 and joining in the general attack on Addington in 1804. On 24 Mar. 1803 he brought the business of the House to a standstill. He was nominated for service on the Okehampton election committee, but had left the House under the mistaken impression that his name had been deleted from the list of Members drawn by ballot. After a lengthy search he was found and hauled before the furious Speaker, who reproved him. He was given minor office in Pitt’s second ministry, was a member of the committee on Indian affairs, 8 May 1805, briefly considered standing as Pitt’s successor for Cambridge University on his death
Lovaine, who dined in conclave with Canning, Rose and other leading Pittites in March 1806, actively opposed the ‘Talents’. He voted against them on the question of Ellenborough’s seat in the cabinet, 3 Mar., the repeal of the Additional Force Act, 30 Apr., and the American intercourse bill, 17 June, and spoke against their army reform proposals, 2 June. Militia business, as he later told Huskisson, prevented him from attending to vote against the militia officers bill, 16 July. When Canning was negotiating with Lord Grenville in March 1807 he named Lovaine as a friend to be provided for, and Grenville, though unable to make a precise engagement, ‘expressed general good disposition’. At the same time Lord Melville noted that Lovaine ought to be ‘competently provided for’ in any administration formed by Pitt’s friends.
He received a salaried place at the Board of Control on the formation of the Portland ministry. He is not known to have made any contribution to debate, but he occasionally acted as a ministerial teller. In August 1808 he went as a volunteer to the Peninsula, regardless, as Lord Auckland censoriously commented, of his official duties and his responsibilities as acting head of the family (his father had been imprisoned in France since 1803), husband of a pregnant wife and father of three young children.
Lovaine tendered his resignation to Perceval in March 1812, almost certainly because of Lord Sidmouth’s impending junction with the ministry, but was prevailed on by the minister to withhold it ‘for his accommodation’. Perceval’s death and Liverpool’s accession to power merely strengthened his determination to resign and he seems to have done so by 21 May. He was expected by the Grenvilles to support his brother-in-law Stuart Wortley’s motion of that day for the formation of a stronger administration but, clearly unable to bring himself to vote with the Whigs, he divided with the ministerial minority against it. In the subsequent negotiations for an alternative government he was disgusted with the ‘arrogance’ of Grenville and Grey, and on 17 June he told Northumberland, who had been reconciled to government since the Regent assumed unrestricted power, that ‘in the present state of the country I should not have systematically opposed any administration’, that he had supported Stuart Wortley’s second motion of 11 June and that he was prepared to rally to the support of the crown. On 7 Aug. he confided to William Fitzgerald, the newly appointed Irish chancellor of the exchequer, that he would have been ‘extremely glad to have gone’ as minister to St. Petersburg, ‘though I dare say I should have been thought presumptuous even in asking for that’. He thought the new ministers had ‘acted most unreasonably’ towards Canning and deplored the presence and influence among them of the Sidmouthites.
Government head-counters listed him as a friend after the 1812 general election, but Rose commented to Arbuthnot, 8 Nov., that while he would ‘probably not be against’, he was ‘at least cool towards the government; dislikes Lord Sidmouth’s connections and is an admirer of Mr Canning’, and would ‘not go up to the meeting of Parliament’. He may well not have done so, for he was ordered to be taken into custody, 22 Feb. 1813.
He later held Household appointments under George IV, William IV and Victoria, and enjoyed the dukedom of Northumberland for two-and-a-half years before his death on 21 Aug. 1867.
