Leland, whose tradesman grandfather migrated from Wigan to Dublin, served under Wolfe at Quebec, and in the West Indies (1762), after which he was for a time on half-pay. Having married a Sussex heiress, he thought of contesting Horsham in 1765, but gave it up.
Leland was returned for Stamford by the Earl of Exeter, as a family friend, on a vacancy in 1796, the year he became lieutenant-governor of Cork. He canvassed in person, though the seat was a safe one.
Leland died 3 Jan. 1808, ‘at an advanced age’. He had sold Strood in 1801 and settled in Surrey. Nearly all his surviving correspondence is on military matters.
