About these notes. This is the sub-topic lookup version of the ministerial responsibility pack. For the narrative lesson, use the Walk-through; for the core basics and the IMR-or-CMR drill, use the Core; for the full case library, the Examples; for the fifty-year arc, the CMR timeline. The cards below open one at a time and cover the two doctrines, the case library, the Code machinery, the CMR arc and the exam method.
Likely exam angles. The 30-mark question lands on whether ministerial responsibility still operates effectively, whether collective responsibility has been fatally weakened, or whether individual responsibility is now meaningless. Each one is covered in the cards below.
Ministerial responsibility is the convention that holds ministers and the cabinet to account in Parliament. It has two halves, and the whole topic turns on telling them apart.
IMR splits into two strands, and they behave very differently.
IMR is now reliable for personal misconduct: misleading Parliament, breach of the Ministerial Code, harassment or bullying. Amber Rudd (2018) resigned over Windrush after inadvertently misleading the Commons about removal targets; Damian Green (2017) went after misleading the PM; Dominic Raab (2023) resigned after an independent inquiry upheld bullying complaints; Suella Braverman (October 2022) resigned over a security breach. If you argue IMR is dead, you have to explain these.
IMR rarely bites for departmental policy failure. The standard exam example is Lord Carrington (1982), who resigned as Foreign Secretary over the Falklands invasion despite no personal fault - precisely because there are so few modern examples to use. Against it sit the non-resignations: Theresa May at the Home Office (2010-16) survived multiple immigration failures, and Gavin Williamson (2020) did not resign over the A-level algorithm fiasco.
CMR works unevenly, and the pattern follows the strength of the Prime Minister.
| Case | Year | Which argument it fits |
|---|---|---|
| Amber Rudd | 2018 | IMR personal - misled Commons over Windrush. The headline modern IMR-personal example. |
| Damian Green | 2017 | IMR personal - misled the PM plus harassment claims. |
| Priti Patel | 2017 | IMR personal - unauthorised meetings with Israeli officials; Code breach on transparency. |
| Liam Fox | 2011 | IMR personal - the Adam Werritty affair; Code breach. |
| Suella Braverman | Oct 2022 | IMR personal - security breach (official document from personal email). |
| Suella Braverman | Nov 2023 | CMR breach - sacked after an op-ed against the cabinet line. |
| Dominic Raab | 2023 | IMR personal - bullying complaints upheld by the Tolley inquiry. |
| Lord Carrington | 1982 | IMR departmental - the classic, and almost the only modern, example. |
| Estelle Morris | 2002 | IMR personal - rare voluntary resignation on honesty grounds. |
| Theresa May (Home Office) | 2010-16 | IMR non-resignation - departmental failures with no resignation. |
| Boris Johnson (Partygate) | 2022 | Both - convention NOT biting; first sitting PM fined for breaking the law. |
| Gavin Williamson | 2020 | IMR non-resignation - the A-level algorithm fiasco with no resignation. |
| 1975 EEC referendum | 1975 | CMR formal suspension - Wilson; the precedent 2016 followed. |
| 2016 EU referendum | 2016 | CMR formal suspension - Cameron; six ministers campaigned Leave. |
| Robin Cook | Mar 2003 | CMR constructive resignation - could not back the Iraq War. |
| Clare Short | May 2003 | CMR delayed resignation over Iraq - the awkward case. |
| Truss-Kwarteng | Oct 2022 | CMR collapse - open briefing against the PM before she fell. |
| Sue Gray report | Jan 2022 | Process - institutional response surviving even when the PM did not resign. |
The convention runs through the Ministerial Code, and the way the Code is enforced is the key to several cases.
The history of CMR is not steady decline. It is a convention whose impact rises and falls with the political strength of the Prime Minister.
| Period | What happened | What it shows |
|---|---|---|
| 1975 | Wilson suspended CMR for the EEC referendum. | Suspended by choice - the first formal suspension. |
| 2010-15 | Coalition - agreed exceptions written into the Coalition Agreement; Cable openly criticised Conservative policy and stayed. | Diluted by design - one voice was impossible with two parties. |
| 2016 | Cameron suspended CMR for the EU referendum; six ministers campaigned Leave. | Suspended by choice - the second formal suspension. |
| 2017-19 | May without a majority; Davis and Johnson resigned over Chequers (July 2018); leaks routine. | Breaking down - a weak PM cannot enforce it. |
| 2019-20 | Johnson reasserts after his 2019 majority; Javid resigned as Chancellor (February 2020) rather than accept No 10 control of his advisers. | Reasserted - a strong PM re-imposes one voice. |
| 2022 | 5 July: mass resignations remove Johnson within two days. Then Truss: the mini-budget bypassed cabinet, ministers briefed openly, the government fell in 49 days. | Collapse - then used as a weapon to remove a PM. |
| 2024- | Starmer reasserts with a large majority; Rayner resigned as Deputy PM in autumn 2025 over a tax dispute. But leaking has stayed routine. | Reasserted - with limits. |
