An unusually close bond of affection existed between Phipps and his elder brother Henry, 3rd Lord Mulgrave. Their military careers followed a similar pattern and Phipps, a bachelor, lived at Mulgrave for much of his life.
Like his brother, Phipps regarded himself as a personal friend of Pitt. His support of Pitt’s administration in his first two Parliaments was confined to intervals in active service. His entry into Parliament had been postponed because he was serving in Flanders. In 1799 he was at Madeira. No contribution to debate is known until 5 Apr. 1803 when he called Sheridan to order for a disparaging reference to Pitt. On 3 June 1803 he supported Pitt’s question for the orders of the day and on 2 Aug. Fox’s amendment for a council of generals. Listed Pitt’s adherent in March 1804, he voted in opposition to Addington on the defence divisions of 23 and 25 Apr. He supported Pitt’s second ministry, in which his brother joined the cabinet, voting against the censure of Melville, 8 Apr. 1805. In October of that year he was reported as exulting in Pitt’s ability to carry on without recruiting extra support, thanks to the King’s firmness. Thomas Grenville quoting him on this described him as ‘one of the most familiar and confidential inmates of the Treasury’.
Phipps, mourning his loss, joined Pitt’s friends in their quarrel with the Grenville ministry, voting against Ellenborough’s cabinet seat, 3 Mar. 1806, against the repeal of Pitt’s Additional Force Act, 30 Apr., and against the American intercourse bill, 17 June. In defiance of ministers he supported the vote of thanks to the volunteers, 11 July. He was listed ‘adverse’ to the abolition of the slave trade. He supported the Portland ministry, in which his brother obtained the Admiralty. Phipps was said to have considerable influence over him.
Phipps’s brother, on exchanging the Admiralty for the Ordnance in 1810, intended him to be his secretary;
Phipps suffered a paralysis of hands and arms in 1797 after ‘drinking bad sherry when in regimental quarters, in which white lead was infused’. He never fully regained the use of his right arm, which ‘hung down like the fin of a turtle’ and earned him the nickname of ‘the Governor of Finland’.
A gentleman of great accomplishments and information, he associated ... with all the men of talent and genius of the day. He himself possessed literary powers of no mean character, and a taste and judgment of no inferior quality. He was always gay and cheerful in society, a kind friend, a hospitable host, and an agreeable companion.
He died in Venice, 14 Sept. 1837.
