‘Cas’ or ‘Young Rapid’, as the rakish Frederick Stewart was known,
Castlereagh returned to England for a period of intensive study under his tutor John Matthias Turner, before going up to Christ Church in January 1823.
Mr. Robinson* [at the board of trade] or your lordship might employ him (out of remembrance to the name he bears) in any of the offices at home in a confidential and private manner, to give him a better habit of office detail, before he came into Parliament.Add. 38298, ff. 190, 192.
Ministers agreed to provide something, in part to keep on friendly terms with the wayward Londonderry, but were still trying to accommodate him two years later.
As early as July 1824 Castlereagh was taking soundings about standing for Down, and his father reported from their residence, Mount Stewart, that month that ‘Frederick has been very handsomely admitted into the Down Hunt, and I think his conduct since his arrival here has given satisfaction’.
Castlereagh presented Down petitions for Catholic relief, 27 Feb., 2 Mar., and voted in this sense, 6 Mar. 1827.
He declined Wellington’s offer of the colonelcy of the South Down militia in February 1829.
Both he and his father were said to be ‘sulky with the duke’ in early 1830, when Castlereagh commented privately that the Commons ‘is in a strange state’ and that ‘we shall be either out of office next week, or stronger than we ever were’.
At Londonderry’s request, on 7 Oct. 1830 Castlereagh reported his grievances to Wellington, who replied that ‘I can quite understand and enter into your uncomfortable position with your father, in being separate in politics. But this is no fault of mine, and he should have thought of this himself’.
He divided against the second reading of the reintroduced reform bill, 6 July, for postponing consideration of the partial disfranchisement of Chippenham, 27 July, and with Hunt to make proven payment of rent a qualification for voting in boroughs, 25 Aug. 1831. He brought up petitions for the grant to the Kildare Place Society, 15 July, 8 Aug., 27 Sept., when he claimed that its discontinuation was unpopular with northern Irish Protestants. He voted against the passage of the reform bill, 21 Sept.; Londonderry’s hostile vote in the Lords the following month led to him being physically attacked by a street mob.
O’Connell observed in October that it was ‘shocking that an Irish county should return a man who bears the odious title of the assassin of his country - Castlereagh’; but, a founder member of the Carlton Club that year, he was again returned as a Conservative for Down at the general election of 1832.
