Unlike his father and uncles, Smith played no part in the family’s banking and financial activities. He was elected to Brooks’s at the age of 19, on 10 Apr. 1815, and, after his return for the family pocket borough at the general election of 1818, signed the requisition calling on Tierney to take the leadership of the Whig opposition in the Commons. From the outset of his career he showed a far more decided commitment to the Whigs than did Lord Carrington and he voted consistently and regularly in opposition to government in the 1819 session. On 18 May 1819 Henry Williams Wynn told his wife, Smith’s sister, that the young man was ‘wrapped up in politics’ and ‘very mad with the Grenville party’, Carrington’s closest associates, over their refusal to support Tierney’s major censure motion.
Thomas Grenville reported in October 1819 that Smith was thought to disagree with Carrington’s alarmist attitude towards the unrest which had followed the Peterloo incident; but according to Charles Williams Wynn it was ‘contrary to expectation’ that he voted for the amendment to the address, 24 Nov.
