Blair’s family had been prominent in Ayrshire for over 600 years and boasted a long tradition of military service. At the county meeting in April 1821 he seconded the petition against any change to the Scottish jury system.
The ministry regarded him as one of their ‘friends’, and he voted with them in the crucial civil list division, 15 Nov. 1830. He presented a synod of Glasgow and Ayr anti-slavery petition, 8 Nov. 1830. He divided against the second reading of the Grey ministry’s reform bill, 22 Mar., and for Gascoyne’s wrecking amendment, 19 Apr. 1831. At the ensuing general election he offered for Ayrshire, maintaining that he was willing to ‘support a moderate and constitutional plan of reform, which would tend to the benefit of the nation and the security of property’, and added opaquely that ‘so far as the present ... bill shall go to assist the manufacturing labourer of this country, I declare to God it shall have my best support’. His return ahead of a local reformer, Richard Oswald, sparked a riot.
At the general election of 1832 Blair stood again for Ayrshire, promising to pursue the same ‘independent’ course, and claimed that he had ‘never separated a regard for [the county’s] agricultural interests from those of its commerce and manufactures, which ... ought ever to be united’. However, he was heavily defeated by Oswald.
