Returned on the family interest at Haslemere, Burrell was independent, and on 18 Apr. 1777 voted with Opposition against payment of the King’s debts; otherwise he usually supported the Government. Most of his recorded speeches are on America, in favour of coercion.
The control of Haslemere having passed to Sir James Lowther, Burrell did not seek re-election in 1780, but on 23 Mar. 1782 was returned for Boston on the Ancaster interest, apparently unopposed, though an opposition had been intended; and he was re-elected in 1784, in a contested election. On 21 Feb. 1783 he spoke against Shelburne’s peace preliminaries, calling them ‘one of the most disgraceful, the most infamous treaties that had ever insulted that or any other House of Parliament’; and advocated recourse to our ‘power to resist’ to avoid such ‘humiliation and degradation of a great and powerful people’. ‘He spoke ... as an independent country gentlemen, who, unconnected with party ... gave vent to his honest indignation’
The luck of the Burrells became almost proverbial with contemporaries—the brilliant marriages of Peter Burrell’s sisters and his own, which proved even more fortunate than could have been expected, when a few months later the sudden death of the 4th Duke of Ancaster left Burrell’s wife the heiress to honours and riches. ‘The fortune of the Burrells is powerful enough to baffle calculation’, wrote Walpole to Lady Ailesbury, 10 July 1779; and A. M. Storer to William Eden, 14 Dec. 1787, ‘Sir Peter Burrell’s good luck is never failing’.
He died 29 June 1820.
