 Yarborough, Boucherett's patron, was an opponent of the administration of William Pitt the Younger and supported the Duke of Portland during the 1790s.Boucherett was an infrequent voter, but he told the diarist Joseph Farington that, when he did vote, he tended to do so with Charles James Fox, rather than Pitt the Younger, although, he later became "disgusted" at Fox's style of opposition; he is also known to have voted against the Ferrol Expedition in 1801.The seat did allow for him to further the interests of the Haven Company, with him proposing a bill to grant more funds in 1799.
