The Chancellor of the Exchequer has appointed Zac Goldsmith to be Steward and Bailiff of the Chiltern Hundreds. The appointment is one of the means by which an MP resigns from the House of Commons.
Zac Goldsmith's resignation will trigger a by-election in the Richmond Park constituency on a date to be announced.
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 accepting an office of the Crown, which automatically disqualifies the MP from holding a seat in the House of Commons.
If an MP indicates that they wish to resign, the Chancellor of the Exchequer grants either the Crown Steward and Bailiff of the Three Hundreds of Chiltern or Crown Steward and Bailiff of the Manor of Northstead by means of a written warrant, in the presence of a witness. These posts are unpaid.
The Member retains the position 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 the same time.
