Earl Alexander of Tunis

Earl Alexander of Tunis is a title in the Peerage of the United Kingdom. It was created on 14 March 1952 for the prominent military commander Field Marshal Harold Alexander, 1st Viscount Alexander of Tunis. He had already been created Viscount Alexander of Tunis, of Errigal in the County of Donegal, on 1 March 1946, and was made Baron Rideau, of Ottawa and of Castle Derg in the County of Tyrone, at the same time he was given the earldom. These titles are also in the Peerage of the United Kingdom. Alexander was the third son of James Alexander, 4th Earl of Caledon.

He was succeeded by his eldest son, the second and (As of 2010) present holder of the titles. He briefly served as a Lord-in-Waiting (government whip in the House of Lords) under Edward Heath from January to March 1974. However, he lost his seat in the House of Lords after the passing of the House of Lords Act 1999. As a descendant of the fourth Earl of Caledon Lord Alexander of Tunis is also in remainder to this peerage and its subsidiary titles. From 1980 to 1990 he was in fact heir presumptive to these titles, before the birth of the current Earl of Caledon's son and heir, Viscount Alexander.
