Bateman inherited from his father property which gave him an interest at Leominster and on the Welsh borders; through his mother he was connected with the Marlborough, Bedford, and Pelham families.
In 1753, Bateman, then representing Woodstock on the interest of his uncle Charles, Duke of Marlborough, was nominated at St. Albans by the Duke, who was nursing the constituency for another nephew, John Spencer, then a minor. Bateman also seems to have acted as Marlborough’s agent there, and was said to have ‘given some umbrage by talking in a very high strain of preserving Mr. Spencer’s interest for him till he came of age by weight of money against all opposers’.
In Parliament Bateman supported Administration. In September 1755, Henry Fox included him in his list of persons to be promoted, adding ‘the most useful man in the House who does not speak’.
In 1768 the seat at Woodstock was needed for Lord Robert Spencer, recently come of age, and Bateman was returned unopposed on his own interest at Leominster. He now constantly supported Administration till the fall of North. On the formation of the second Rockingham Administration he lost his post as master of the buckhounds; does not appear in any division list before he left Parliament in 1784; and was classed as ‘absent’ by Robinson in January 1784. Wraxall, who knew him ‘with great intimacy’, writes:
No individual ... was more personally regretted by the King than Lord Bateman ... The frankness and gaiety of his disposition rendered him peculiarly agreeable to the Sovereign. At near seventy years
In 1782 Bateman was sixty-one. of age Lord Bateman preserved all the activity of youth, accompanied by an elasticity of mind and character which never forsook him. He might have been reinstated in the employment of master of the buckhounds under succeeding Administrations but he preferred the enjoyment of personal liberty, and passed the last years of his life principally at his seat of Shobdon. His understanding was good, though he loved pleasure of every description more than business, and he possessed that mediocrity of talents which never inspiring awe, forms the best recommendation to royal favour.Mems. ii. 275-6.
He died 2 Mar. 1802.
