Duff and his elder brother James were removed by their uncle, the 2nd Earl Fife, from parental care and, more specifically, the baneful influence of their immoral Skene mother, in 1783. They were schooled first at Banff and then at Westminster, whence James went to Oxford. Alexander, who was described by Fife as ‘a good boy but [with] no constant application’, was destined for the army, and his family connections secured him rapid promotion in the newly formed 88th Foot, with whom he served in Flanders until the evacuation. In March 1795 Fife reported that ‘Alex Duff is here, very thin; has been advised on the continent to drink gin and smoke tobacco; I hope he will leave that off, otherways he shall vex me worse’.
At the general election of 1820 his brother, who had succeeded as 4th Earl Fife in 1811, put him forward for Elgin Burghs in a bid to overturn the Kintore-Grant electoral pact. After a campaign involving violence, kidnappings and legal chicanery, Duff lost to Lord Kintore’s nominee by the casting vote of the delegate from Cullen, the returning burgh. The petition lodged in his name was not pursued.
taken it into his head that ... General Duff might be anxious to retire, and he employed a mutual friend ... to sound him. Duff complained a good deal of the expense to which he has been put, but did not seem to entertain any thought of withdrawing himself from the chance of renewing it by another London campaign ... It remains to be seen whether anything amounting to a hint that if he wants to retire salutary means may be found to fill up his place without putting Fife’s interests to hazard by a contest would be likely to move him. I do not build much on this.Add. 38752, f. 176.
Nothing came of it. When Lord Nugent moved to curb army flogging, 10 Mar. 1828, Duff, who cited the authority of ‘that great captain’ (and now prime minister) the duke of Wellington to support his assertion that ‘everything depends on discipline’, provoked sniggers, from the ‘facetious’ Hume among others, with his ululation, ‘Oh, my dear House of Commons, consider well before you interfere with the army!’ He was credited with a vote in the minority of nine for removal of the ban on the use of ribbons at elections, 20 Mar. He presented petitions for reform of the Scottish gaols system, 1 May, and the lifting of restrictions on anatomical studies, 5 May. He paired against Catholic relief, 12 May 1828. He was absent from the divisions on emancipation in March 1829, defaulting on a call of the House on the 5th. He left no other trace of parliamentary activity in that or the following session. After his unopposed return for Elgin Burghs at the general election of 1830 ministers listed him as one of their ‘friends’, but he was absent from the crucial division on the civil list, 15 Nov. 1830. He voted against the second reading of the Grey ministry’s English reform bill, 22 Mar., but on 18 Apr. he opposed Gascoyne’s wrecking amendment, explaining:
I am by no means an enemy to reform; but the reform I am friendly to, as I have already expressed to my constituents, is one that would be wholesome and salutary, and consistent with the feelings and wishes of the country.
He was one of the four opponents of the second reading who voted with government against Gascoyne next day. He retired from Parliament at the ensuing dissolution and obtained the colonelcy of the 37th Foot soon afterwards.
Duff, who was knighted in 1834, died at Percy Cross, Walham Green, Fulham, Middlesex in March 1851.
