Griffith, who regularly served as chairman of the Denbighshire bench, had come in for Denbigh Boroughs in 1818 on the Biddulph interest (then in minority), his candidature having been suggested and endorsed by Denbigh corporation, of which he was recorder, William Shipley, dean of St. Asaph, and William Hughes* of Kinmel Park, and sanctioned by the county Member, Sir Watkin Williams Wynn of Wynnstay.
He proved as hitherto to be a staunch member of the Whig opposition ‘Mountain’ to the Liverpool ministry, and also divided unstintingly with Hume until 1824, often in very small minorities.
Tierney requested his attendance in the Commons by 25 Jan. 1821. He continued to support the parliamentary campaign on the behalf of the queen, but although present for most of the debate, he apparently left before the division on her allowance, 31 Jan., having received news that his son George had been captured by Neapolitan bandits and held to ransom.
The line of the Holyhead road over Bryn-y-Garn had been settled to his liking, but he was annoyed during the recess to find that the Williams Wynns now denied him the gaming rights he had enjoyed for 40 years over the Llansannan hills. Trusteeship of the Plasnewydd estate, which had formed part of his marriage settlement, involved him in preparations for further chancery litigation early in 1823.
Griffith, whom Lady Delamere described as ‘the greatest bore in England or Wales (with a constant and alternate flow of words out of his mouth and brandy into it)’, remained an active spokesman in county and borough politics.
