Byng, a professional soldier and distinguished veteran of the Peninsular campaigns and Waterloo, had assumed command of the Irish army under the Tory administration of the duke of Wellington in May 1828. His co-operation with the incoming Grey ministry over appointments in 1830-1 so impressed the reappointed viceroy Lord Anglesey, father-in-law of his eldest son George, that Anglesey endorsed his candidature for county Londonderry as a reformer at the 1831 general election. His unexpected defeat ‘on behalf of the government’ at a personal cost of over £2,000 upped his credit further, and after a series of abortive attempts to find him a berth, the Whigs helped him to come in for Poole on a vacancy in October 1831.
Byng, who joined Brooks’s, 13 Feb. 1833, loyally supported the Whig ministries of Lords Grey and Melbourne when present, but was not a regular presence in the division lobbies and spoke only occassionally on military and Irish matters. ‘Reluctantly’ he acknowledged the necessity of the Irish Coercion Act, 27 Feb., and flogging in the army, which he had suspended temporarily without success in his own command, 2 Apr. 1833. Later that month he appeared, somewhat incongruously, on the platform of the metropolitan meeting for repeal of the assessed taxes, but did not speak.
On 12 May 1835 Byng, who had unsuccessfully solicited a peerage for himself after his elder brother had declined one in September 1831, was created Lord Strafford by the Melbourne administration (a title he took from his maternal grandmother’s father), much to the irritation of the representative of another branch of the family, Earl Fitzwilliam (as Lord Milton had become). Appointed as a ministerial whip in the Lords, his fellow recipient of a barony Lord Hatherton (formerly E. J. Littleton) sniped that he was unfit for the post, being ‘a perfect old woman, totally devoid of the address and tact requisite for the task’, and there was evidently some disappointment at his mustering of the troops during the passage of the English municipal corporations bill and Irish church bill that summer.
Byng, who was elevated to an earldom by the Russell administration in September 1847, died the second oldest member of the Lords in June 1860, ‘after a very short illness’. He was succeeded in his titles and estates, which included the family seat inherited from his childless brother George in 1847, by his eldest son George Stevens Byng (1806-86), a minor Whig officeholder who succeeded him in the representation at Poole.
