The chief interest in Selkirkshire was that of its hereditary sheriff, John Murray of Philiphaugh, who returned his brother-in-law, John Pringle, from 1715, and in 1730 another kinsman, James Rutherford, both government supporters. In 1734 and 1741 Murray himself was returned unopposed as an opposition Whig, having resigned his hereditary sheriffdom to one of his sons. In 1747 he was opposed by a government candidate, Lord Charles Scott, who died before the election, whereupon an unknown candidate stood unsuccessfully against him.
Number of voters: 31 in 1757
