Ministerial responsibility - both individual (IMR) and collective (CMR) - is one of the small set of Section B essay topics Edexcel returns to often. There has not been a 30-mark essay directly on the doctrines since 2021. Four years is a long wait for one of the spec's central conventions, so the topic is overdue.
Four recent events make a Q2(a) on ministerial responsibility very likely this summer. First, Suella Braverman resigned as Home Secretary in October 2022 over a security breach, was re-appointed within days by Rishi Sunak, then sacked again in November 2023 over an unauthorised newspaper article on protest policing - a single career that tests every part of the IMR doctrine. Second, Angela Rayner resigned as Deputy Prime Minister and Labour deputy leader in autumn 2025 over a tax dispute; a serving Deputy PM resigning is rare and high-profile. Third, the Liz Truss mini-budget of September 2022 bypassed Cabinet entirely - a textbook CMR failure followed by collapse of the government in 49 days. Fourth, the 2025 examiner report said the strongest answers used named recent ministers (Patel, Braverman, Williamson, Rayner) rather than older textbook examples (Carrington 1982). All four point to a 30-mark essay on this area.
This is a Section B 30-mark essay. Marks split roughly equally between AO1 (your knowledge of the doctrines and the cases), AO2 (analysis of why each case fits the line of argument) and AO3 (your judgement, which must be picked at the start and held to the end).
A minister is accountable to Parliament for their own conduct AND for the work of their department. The classic sanction is resignation or sacking. The doctrine has two strands. The personal strand says a minister must resign for serious personal misconduct (financial impropriety, bullying, lying to Parliament, security breaches). The departmental strand says a minister must resign for serious policy failure or major operational failure inside their department, even if they did not personally cause it.
All ministers must publicly support government decisions or resign. The doctrine is what keeps Cabinet government coherent in public - it means the government speaks with one voice and a minister who cannot defend a policy must leave. CMR has been formally suspended only a handful of times (the 1975 EEC referendum and the 2016 EU referendum, both by the PM) but is increasingly described as eroded by routine leaking, public briefing against colleagues, and PM tolerance of public disagreement.
This side argues the doctrines have been bent so often that they now describe practice less than they used to, and parliamentary mechanisms for enforcing them are weak. The evidence falls into five areas: IMR enforced selectively, CMR routinely breached, the Ministerial Code as PM-controlled, Special Adviser opacity, and the weakness of parliamentary sanctions.
In November 2020 the Cabinet Office's independent adviser Sir Alex Allan found Home Secretary Priti Patel had bullied civil servants. Bullying is a clear breach of the Ministerial Code. Boris Johnson rejected the finding and kept Patel in post. Sir Alex Allan resigned in protest. This is the textbook case for the agree side - a clear breach of IMR met no sanction because the PM chose not to enforce it. The trigger for resignation is not departmental failure or misconduct. It is whether the PM still wants the minister.
On 23 September 2022 Kwasi Kwarteng delivered a 45 billion pound mini-budget written by a small group of free-market advisers from Tufton Street think tanks. It was not discussed in Cabinet. The Office for Budget Responsibility was not asked to forecast its effects. Cabinet ministers heard the detail at the same time as MPs. CMR was not so much breached as never engaged - there was no collective decision to be collectively responsible for. The 2022 case is the strongest single example of CMR's modern collapse.
Cabinet discussions leak routinely under Johnson, Truss, Sunak and Starmer. Briefings against colleagues are reported in The Times, the Guardian and the Telegraph the morning after every contentious Cabinet meeting. Angela Rayner's allies were briefing against the Treasury position throughout autumn 2025 before her resignation. CMR formally requires public support; what we have is public dispute managed through anonymous briefing.
The Ministerial Code sets standards but is owned and enforced by the Prime Minister. Sir Alex Allan resigned in 2020 over Johnson's handling of Patel. Sir Christopher Geidt resigned in June 2022 over Johnson's failure to consult him on potential trade-rule breaches. Three different Independent Advisers on Ministers' Interests have served since 2020 (Allan, Geidt, Sir Laurie Magnus). The Code is only as strong as the PM's willingness to enforce it - which makes it a weak external check.
Select committees can investigate (the Liaison Committee questions the PM directly) but their recommendations are not binding. The Public Accounts Committee exposed major failings on PPE Medpro, partygate and Greensill but could not enforce sanctions. Urgent questions force ministers to appear but do not compel honest answers. Parliament's only real sanction is to defeat the government in a no-confidence vote - the nuclear option, which removes the entire government, not the individual minister.
| Case | Year | What it shows |
|---|---|---|
| Priti Patel bullying | 2020 | Independent finding of Code breach; PM kept minister; Code adviser resigned |
| Truss / Kwarteng mini-budget | 2022 | Major fiscal package without Cabinet discussion - CMR not engaged |
| Cabinet briefings as norm | Ongoing | Public disagreement managed via leaks not resignations |
| Sir Christopher Geidt resignation | 2022 | Second Code adviser to resign in two years |
This side argues that despite the high-profile breaches, ministers do still resign when the political weight of breach is enough, and the doctrines still constrain Cabinet behaviour in ways less visible than the headline failures. The evidence falls into five areas: ministers who have resigned, the threat of mass resignation, the survival of CMR in big moments, the Wright reforms strengthening select committees, and the Sue Gray and partygate accountability chain.
Gavin Williamson lost his job as Education Secretary in September 2020 over the A-level results algorithm fiasco. Suella Braverman resigned as Home Secretary in October 2022 over a security breach (sending Cabinet documents from a personal email) and was sacked in November 2023 over an unauthorised newspaper article. Dominic Raab resigned as Justice Secretary in April 2023 after a bullying inquiry by Adam Tolley KC. Angela Rayner resigned as Deputy PM in autumn 2025 over a tax dispute. The disagree side reads these as the doctrine working - serious breach met serious sanction.
On 5 July 2022 Rishi Sunak and Sajid Javid resigned from Boris Johnson's Cabinet within minutes of each other. Over the next 48 hours more than fifty ministers and aides followed. Johnson resigned within two days. This is what CMR looks like when it bites - Cabinet ministers withdrawing support en masse to bring down a PM who has lost their confidence. The doctrine does not depend on every breach being punished one by one. It depends on Cabinet ministers retaining the collective option of mass resignation, which they have used twice in the last four years (against Johnson in 2022, against Truss in October 2022).
The agree side uses Truss to show CMR collapsing. But the Truss case also proves both doctrines still work in the end. Truss's mini-budget bypassed Cabinet (CMR breach). The result was the shortest premiership in British history - 49 days. Jeremy Hunt was effectively imposed on her by the parliamentary Conservative Party. Cabinet ministers either resigned or refused to defend her. The doctrines bit hard once they engaged.
The 2010 Wright reforms made select committee chairs elected by the whole House, not appointed by the whips. The change has produced more independent committees - the Liaison Committee, Public Accounts Committee, Treasury Select Committee and Home Affairs Select Committee have all extracted ministerial concessions and forced ministerial appearances over the last decade. Margaret Hodge's PAC under Cameron exposed corporate tax avoidance. Meg Hillier's PAC exposed PPE Medpro failures. The post-2010 select committee system is a much sharper check than the pre-2010 one.
Sue Gray's report into Downing Street parties (May 2022) ultimately contributed to Boris Johnson's resignation as PM in July 2022 and his resignation as an MP in June 2023 after the Privileges Committee found he had lied to Parliament. Lying to Parliament is the oldest and clearest IMR breach. The fact that a sitting MP was forced out by a Privileges Committee finding shows the doctrine still has teeth at the most serious end.
| Case | Year | What it shows |
|---|---|---|
| Williamson exams algorithm | 2020 | Resignation for departmental failure (IMR departmental strand) |
| Sunak / Javid mass exit | 2022 | CMR through threat of collective withdrawal - PM forced out |
| Raab bullying inquiry | 2023 | Resignation following independent Tolley report |
| Johnson Privileges Committee | 2023 | Lying to Parliament finding; resigned as MP |
Edexcel mark schemes are clear: top-band answers commit to one of the two views and defend it the whole way through. Fence-sitting answers stay at Level 3.
For this question, the stronger side is the agree side: ministerial responsibility no longer effectively holds the executive to account. The Patel case (2020) shows the PM can simply ignore a Code finding. The Truss mini-budget (2022) shows CMR can be entirely bypassed on a 45 billion pound fiscal decision. Cabinet leaks are now the norm. Two Independent Advisers on Ministers' Interests resigned in two years (Allan 2020, Geidt 2022). The doctrines have become PM-controlled conventions enforced selectively. The disagree side's evidence (Williamson, Braverman, Raab, Rayner resigning) shows what the doctrines look like when the PM CHOOSES to enforce them - which is not the same as the doctrines effectively holding the executive to account.
So back the agree side. Use the disagree side's evidence (mass resignation against Johnson, the Wright reforms, the Privileges Committee finding on Johnson) to build counter-arguments, then knock them down by showing they are crisis-only enforcement rather than day-to-day accountability.
The view in the question is correct: ministerial responsibility no longer effectively holds the executive to account. Both IMR and CMR have become PM-controlled conventions enforced selectively. Disagree-side evidence (ministers do resign; mass resignation forced Johnson out) shows the doctrines bite in extremis, but day-to-day accountability has weakened sharply. The agree side wins.
