Principle by which ministers must support all decisions of government in public or resign
What is the purpose of collective ministerial responsbility?
To maintain unity of the government in face of attacks by the opposition
While ministers are free to argue their case with each other in private, once a decision has been reached it is binding on them all. If a minister cannot accept such a decision, in theory they should resign.
Example of a minister that resigned due to not being able to uphold collective ministerial responsibility
RobinCook in 2003, leader of the House of Commons, in opposition to the Blair government’s decision to go to war with Iraq
