Shadow Chief Whip, Rosie Winterton, moved the Writ for the Barnsley Central by-election on Wednesday 9 February in the House of Commons.
The moving of the Writ follows the appointment of Eric Illsley to the office of Steward and Bailiff of the three Chiltern Hundreds of Stoke, Desborough and Burnham. A by-election will take place on Thursday 3 March in the Barnsley Central constituency.
How an MP vacates their seat
A resolution passed by the House of Commons on 2 March 1624 prohibits MPs directly from resigning their seats. Death, disqualification and expulsion are the only means by which a Member’s seat may be vacated during the lifetime of a Parliament.
An MP who wishes to resign has to go through the process of applying for a paid office of the Crown, which automatically disqualifies the MP from holding a seat in the House of Commons. There are two offices which MPs can apply for, Crown Steward and Bailiff of the Chilterns Hundreds and of the Manor of Northstead.
An MP wishing to resign applies to the Chancellor of the Exchequer for one of the offices, which he or she retains until the Chancellor appoints another applicant or until the holder applies for release from it. (Every new warrant issued revokes the previous holder). It is usual to grant the offices alternately; as this enables two Members to retire at precisely the same time.
