Hon. the Lady Herries of Terregles in 2010. Lord Lothian also sat as a Conservative MP, and was given a life peerage upon retirement from the Commons. Despite already succeeding to his titles, he did so after the House of Lords Act 1999 removed the automatic right of hereditary peers to sit in the Lords, and so required a life peerage to be able to sit there. Lord Lothian married the 16th Lady Herries of Terregles in 1975. Her elder sister, the 14th Lady, married the cricketer Colin Cowdrey in 1985. Cowdrey was given a life peerage by outgoing Prime Minister John Major in 1997.

He was later given a life peerage in 1979 when he was appointed to the role of Lord High Chancellor of Great Britain. His daughter-in-law was likewise ennobled for life as was her father. The 3rd Viscount was also given a life peerage, which enables him to sit in the House of Lords following the House of Lords Act 1999, which automatically excludes most hereditary peers. The life peerages are

Just under a year before succeeding to the Earldoms, Robert Lindsay (then styled Lord Balniel) was given a life peerage. It is notable that he entered the House of Lords in this way, as he could conceivably have entered by writ in acceleration using one of his father's junior titles (such as the Wigan Barony, or even the Lindsay and Balniel Lordship of Parliament, with which was then styling himself).
