Blackett succeeded in 1680 to his father’s business and to the magnificent town house which he had purchased from Sir Francis Anderson. Although he did not support the surrender of the Newcastle charter in 1684, he was one of the two aldermen sent to London to secure a replacement. They were described by the Duke of Newcastle (Henry Cavendish) as ‘very rich and of great reputation for understanding and honesty’. He defeated Henry Brabant, one of the court candidates, at the general election of 1685, and became a moderately active Member of James II’s Parliament. He was appointed to the committees on the bills for the encouragement of woollen manufactures, the rebuilding of St. Paul’s, the prohibition of imported tallow candles, and the relief of London widows and orphans. He successfully resisted Brabant’s attempt to nominate the entire common council in November, but was himself removed from the corporation in 1687. To the lord lieutenant’s questions on the repeal of the Test Act and Penal Laws he replied provocatively on 9 Feb. 1688

Blackett was returned unopposed to the Convention, in which, according to Ailesbury’s list, he voted to agree with the Lords that the throne was not vacant. During April 1689 he was appointed to the committees to consider the bills for the naturalization of Schomberg and the export of beer, ale and mum, to hear complaints against customs officials, and to draft an address of thanks to the King for his care of the church. But he was not an active Member, his only other committee being on the bill for a ‘court of conscience’ for small claims in Newcastle (20 May), which he probably introduced. In September he bought Wallington from
