In 1791 when Lady Malmesbury met him in Italy she described Lord Bruce as ‘quite Lord Ailesbury just out of the shell—which, by the by, is no bad comparison, for they are like unfledged turkeys’. Soon afterwards he crossed her path again: ‘a sad goose, but a good humoured creature and so desperately in love with the Duchesse de Fleury it is quite melancholy. Lord Malmesbury says he is in love like a rabbit with a bunch of parsley.’
At the first opportunity after he came of age Bruce was returned by his father for the family borough of Marlborough, for which he sat until his father died. Ailesbury also wished him to have the management of his electoral interest. As the son of a courtier, he was expected to be well disposed to administration. In fact he was not an enthusiastic attender, occasionally deserted the government, without going into systematic opposition, and never justified his conduct in the House. For instance, he joined the opposition division for inquiry into the failure of the Ferrol expedition, 19 Feb. 1801,
Bruce thought that his and his father’s support of the Portland administration in 1807 might be rewarded with a marquessate if they applied for it. (Ailesbury did apply, without success.)
Bruce achieved his ambition of a marquessate at the coronation of George IV, whose tutor his father had been. His politics became ultra conservative. He died 4 Jan. 1856.
