An office of profit is a term used in a number of national constitutions to refer to executive appointments. A number of countries forbid members of the legislature from accepting an office of profit under the executive as a means to secure the independence of the legislature and preserve the separation of powers.

No person who has an office under the monarch, or receives a pension from the Crown, can be a Member of Parliament (MP). This provision was inserted to avoid unwelcome royal influence over the House of Commons. It remains in force, but with several exceptions. (As a side effect, this provision means that MPs seeking to resign from parliament can get round the age-old prohibition on resignation by obtaining a sinecure in the control of the Crown; while several offices have historically been used for this purpose, two are currently in use: appointments generally alternate between the stewardships of the Chiltern Hundreds and of the Manor of Northstead.[10])

Državni službenik ne može biti član donjeg doma (izmijenjeno 1706.; ako član Donjeg doma primi položaj ministra gubi mandat, a na raspisanim dopunskim izborima i on se može kandidirati, pa ako bude izabran može biti i ministar i član donjeg doma; ai je ostalo opće pravilo da članovi donjeg doma ne mogu biti državni službenici, osim ministri; pravilo reizbora posve je ukinuto 1926.)
