_Members of Parliament (MPs) wishing to give up their seats before the next general election are appointed to an office which causes the MP to be disqualified from membership. Historically, all "offices of profit under the Crown" could be used for this purpose. Only two are still in use:[2][3]
Crown Steward and Bailiff of the three Chiltern Hundreds of Stoke, Desborough and Burnham
Crown Steward and Bailiff of the Manor of Northstead
The stewardships are unpaid positions that provide no benefits and carry no responsibilities.[4] The Chiltern Hundreds last required an actual Steward in the 16th century. The main property of the Manor of Northstead was described in 1600 as "unfit for habitation" after "it fell down".[5] The stewardships have been maintained as nominal offices of profit solely as a legal fiction to meet the requirements of the House of Commons Disqualification Act 1975[2][6] and its predecessors.
The offices are used alternately, making it possible for two members to resign at the same time. When more than two MPs resign at a time—for example, when 15 Ulster Unionist MPs resigned in protest at the Anglo-Irish Agreement on 17 December 1985—the resignations are, in theory, not simultaneous but spread throughout the day, enabling each member to hold one of the offices for a short time. The former office-holder may subsequently be reelected to Parliament.[2]_
So - until another MP resigns, you can't be re-elected? They will be holding one positions above?
