Like his uncle Lord Caledon, Alexander proceeded to India, where he too made a fortune. He owed much to the protection of Josias Du Pré Porcher.
Alexander was on the list of Treasury supporters after his re-election in 1812. He voted steadily against Catholic relief in the ensuing Parliament, and as steadily against Christian missions to India in the session of 1813, when he was a member of the select committee on East India Company affairs. His first known speech was on this subject, 22 June 1813. So far as is known, he voted only with ministers, even when they were in the minority, as on 3 July 1815, 18 Mar. and 17 June 1816. He seldom spoke, but went out of his way to defend the property tax, 18 Mar. 1816. He supported the suspension of habeas corpus and its consequences, 23 June 1817, 10 Feb. and 5 Mar. 1818. In the Parliament of 1818 he silently supported ministers on Wyndham Quin’s case, 29 Mar., against Tierney’s censure motion, 18 May, and on the foreign enlistment bill, 10 June 1819. Alexander died 12 Sept. 1848.
