All students at the university are eligible to vote in the election of the Rector (officially styled "Lord Rector"), who holds office for a three-year term and chairs the University Court. In the past, this position has been a largely honorary and ceremonial one, and has been held by political figures including William Gladstone, Benjamin Disraeli, Bonar Law, Robert Peel, Raymond Poincaré, Arthur Balfour, Charles Kennedy and 1970s union activist Jimmy Reid, and latterly by celebrities such as TV presenters Arthur Montford and Johnny Ball, musician Pat Kane, and actors Richard Wilson, Ross Kemp and Greg Hemphill. In 2004, for the first time in its history, the university was left without a Rector as no nominations were received. When the elections were run in December, Mordechai Vanunu was chosen for the post, even though he was unable to attend due to restrictions placed upon him by the Israeli government. In 2014, Edward Snowden, an American computer specialist, a former Central Intelligence Agency (CIA) employee, and former National Security Agency (NSA) contractor—who came to international attention when he disclosed a large number of classified NSA documents to several media outlets—was elected. The current Rector, elected on 21 March 2017, is Aamer Anwar, a Scottish lawyer and former student of the university.
