North was very much his father’s son, easy-going, dissipated, frank and humorous and completely over-shadowed by him until 1790. He joined the Whig Club, 17 Jan. 1785. His previous part in bringing about the Fox-North coalition, if a small one, was not forgotten by George III, whose benevolence towards the family was pronounced and who thought that his former prime minister’s son should hold better opinions. When rumours of a dissolution started in 1789, he discovered that his grandfather was unwilling to advance £3,000 for his re-election at Wootton Bassett. Though prepared to purchase a seat, he preferred ‘an annuity’ to a lump sum. There was a possibility of his contesting Dover, but he came in for Petersfield on the Jolliffe interest, soon afterwards succeeding his father to the family seat at Banbury.
North, a ‘powerful but not an elegant speaker’, resumed opposition on 13 Dec. 1790, when he criticized the convention with Spain. On 12 Apr. 1791 he made what Fox called an ‘incomparably good’ speech critical of the government’s bellicose stand against Russia. The likeness to his father’s debating manner was remarked upon.
He died 20 Apr. 1802, after a lingering illness brought on by a spinal injury sustained during his courtship of his second wife, who brought him a bill of sight for £150,000, but no surviving son and heir.
