Blachford was returned to Parliament by his uncle Sir John Barrington, 9th Bt. He had to pay for the privilege like all Barrington’s guests, owning only one burgage in the borough. He made his maiden speech on 29 Feb. 1808, supporting ministers in their conduct of war. On 11 Mar. he took leave of absence and a few months later accompanied Sir Arthur Wellesley to Portugal ‘as an amateur’.
I will take care of him ... He shall see everything that is to be seen, and if he can, then return to England when he will be tired of us. If he should take a commission in the army, he would be obliged to stay longer than is now his intention, or than would suit his other views and objects. If upon trial he should like the life of a soldier, there will be no difficulty in giving him a commission when he shall be abroad.
Blachford came home full of admiration for Wellesley, whose Vimeiro campaign he praised and whose reputation he defended in the House, 25 Jan. 1809. Report had it that he was to have seconded the address and the reporter, Lord Temple, described him as a friend of George Canning, who, he added, must be remaining in office, else Blachford would not ‘put himself forward’. It was as a follower of the Wellesley party, however, that Blachford voted for investigation of alleged ministerial corruption 25 Apr. 1809, the intention being to oust Castlereagh from the War Office for Lord Wellesley’s benefit.
‘A man of profuse expense’,
He remained an adherent of Canning, like him opposing the vice-chancellor bill and supporting sinecure regulation and Catholic relief in 1813. Having disbanded his party at the close of that session, Canning did not forget his satellites when he negotiated with the prime minister for office in July 1814, and Blachford was earmarked to accompany him to Lisbon as secretary of embassy. At first, however, he was given a seat at the Admiralty board. When his health began to break down later that year, Canning discouraged his wintering in Lisbon on the grounds of the expense, but fully intended that he should join him officially when the time was ripe.
