Barnard’s father, Lord Darlington, who was worth over £1,000,000 and owned almost 100,000 acres when (as marquess of Cleveland) he died in January 1842, returned Members in this period for Camelford, Ilchester, Totnes, Tregony and Winchelsea. He also had decisive interests in Milborne Port (until 1825), Shrewsbury, Shropshire and county Durham, where he was colonel of the militia and lord lieutenant.
Barnard’s votes were subject to confusion with those of the Irish Members Lord Bernard and Thomas Bernard. He seems to have divided with the main Whig opposition with Darlington’s Members on most major issues in the 1820 Parliament. According to a radical publication of 1825, he ‘attended frequently and voted in opposition to government’, but his attendance was no more than episodic, and he made no reported speeches and served on no major committees.
Now on half-pay, he retained a low profile in the House until 1830, when his father went over to the duke of Wellington’s administration. He voted for Catholic relief, 6 Mar., and inquiry into the allegations against Leicester corporation, 15 Mar. 1827. He was in France with his youngest brother Harry when Canning succeeded Lord Liverpool as premier, so his allegiance to his administration and to its successor led by Lord Goderich, to whom Darlington owed his promotion to the marquessate of Cleveland, was not tested.
Ministers had passed over him as mover of the 1829 address, and his selection in 1830 was interpreted by the Whig James Abercromby as a deliberate ploy to allay the opposition of Henry Brougham, who despite Cleveland’s entreaties, had exchanged his Winchelsea seat for the Whig duke of Devonshire’s borough of Knaresborough.
Ministers listed Darlington among their ‘friends’, and he divided with them on the civil list when they were brought down, 15 Nov. 1830. In December, Cleveland, who had applied to Wellington in vain for promotion in the peerage, the Order of the Bath, or the Garter, declared for Grey’s reform ministry and expected his sons to do the same.
Out of Parliament, Darlington, like Powlett, moved to Norfolk, settling at the Vane estate of Snettisham Hall, near King’s Lynn. At the general election of 1832 his father’s former Shropshire Member Cressett Pelham made way for him in the Conservative stronghold of Shropshire South, which he represented until Cleveland’s death in January 1842.
