Cary succeeded his father in the viscountcy in 1984 and sat in the
House of Lords with the
Social Democratic Party (SDP), later joining the
Liberal Democrats. Following the removal of the majority of hereditary peers under the
House of Lords Act 1999, he was one of the ninety-two
elected to remain. In 2011 Falkland left the Liberal Democrats and sat as a
Crossbencher until his retirement in 2023. He is a patron of
Humanists UK, and has been a vice-president of the
Royal Stuart Society since 2015 (his ancestors were ardent
Jacobites, and he holds the title of 10th Earl of Falkland in the
Jacobite Peerage). ==Family==
