 It is often thought improper for elected MPs to take instructions solely from non-elected party officials or from the small subset of the electorate represented by party members.In any case, the exigencies of government, the need to cooperate with other members of the legislature and the desire to retain the support of the electorate as a whole often preclude strict adherence to the wider party's wishes.The exact relationship between the parliamentary party and the party varies between countries, and also from party to party.
