Overview of The Rest Is Politics with Johnny Mercer
In this episode, Alistair Campbell and Rory Stewart interview Johnny Mercer, the former Conservative MP, Veterans Minister, and British Army officer, about why Westminster “breaks” politicians, how political incentives reward performance over truth, and why Britain is struggling to adapt to modern defence realities. The conversation also gets deeply personal, covering Mercer’s strict religious upbringing, his OCD and mental health, his relationship with power and authority, his time in government, and his campaign for veterans and Northern Ireland soldiers.
Key Themes
Westminster culture and political decay
Mercer argues that Parliament and Whitehall are shaped by a culture of:
- Inauthenticity and performance
- Tokenism over delivery
- Lies, evasions, and broken promises
- Rewards for ambition and tribalism rather than competence
He is especially critical of:
- PMQs as theatre, not serious scrutiny
- Whips and special advisers who he felt had little real-world understanding
- The media’s role in reinforcing the Westminster bubble
His core point: the system does not reliably select for people with the right moral character.
Politics as delivery, not status
Mercer says he was never interested in politics as a path to influence or celebrity. He treated it as a tool to force action for the people he represented:
- veterans
- constituents in Plymouth
- families affected by addiction, mental health, and social services failures
He openly admits this made him difficult to work with and “friendless” at times, but says he has no regrets because it helped move the dial.
Veterans, War, and Government
Why he entered politics
Mercer says his military service, especially in Afghanistan, left him with deep admiration for ordinary service personnel and anger at how poorly veterans were treated. That frustration became his political mission:
- build proper mental health pathways
- improve prosthetics and rehabilitation
- create a real Office for Veterans’ Affairs
- end the legal harassment of Northern Ireland veterans
Northern Ireland veterans and “lawfare”
He is scathing about attempts to prosecute elderly veterans decades later for actions taken during the Troubles, arguing that:
- the state had previously made commitments to them
- it is morally wrong to apply today’s standards retrospectively in these cases
- senior political and military leaders failed to defend these soldiers until he did
He says he helped:
- create the UK’s first Office for Veterans’ Affairs
- secure legislation to end prosecutions of Northern Ireland veterans
- shift the political conversation on veterans care
- raise veterans spending to £6.5 billion a year
Afghanistan inquiry
Mercer draws a clear line between:
- Northern Ireland legacy cases he sees as politically and morally mishandled
- serious Afghanistan allegations, which he says must be fully investigated
He is emotional about the human cost of the Afghanistan war and says politicians and the public have too easily forgotten the families and the dead.
Mental Health, OCD, and Childhood
Growing up in a strict religious household
Mercer describes a childhood in a highly restrictive, “cult-like” Baptist environment:
- no television
- no pop music
- rigid moral rules
- a very insulated worldview
He says this distorted his understanding of normal life and contributed to long-term psychological damage.
Living with OCD
One of the most powerful parts of the interview is his account of chronic OCD. He rejects the “cute” or fashionable version of OCD and describes it as:
- relentless
- humiliating
- rooted in fear and compulsive rituals
- something that affects daily functioning, sleep, and relationships
He says many people misunderstand OCD and PTSD by trivializing them. His message is that these conditions are real, disabling, and deserve more empathy and less performative sympathy.
Defence and the Future of Warfare
Britain is thinking about war the wrong way
Mercer argues that the British defence establishment is stuck in the past. His main claims:
- modern warfare has changed dramatically
- Ukraine has shown how fast innovation, drones, and adaptability matter
- Britain is still over-fixated on legacy platforms and structures
What matters now
He says the real strategic issues are:
- AI sovereignty
- technological agility
- distributed, adaptable military capability
- learning from Ukraine’s speed and urgency
He is highly critical of the traditional “military mafia” in the UK that resists change and rewards old assumptions.
Advice for future defence leadership
Mercer’s broad recommendation is to:
- think more radically
- listen to people with operational and technological experience
- stop rewarding complacency
- build defence policy around the realities of contemporary conflict, not nostalgia
Plymouth and Local Politics
Why Plymouth matters to him
Mercer speaks warmly about Plymouth as:
- physically beautiful
- shaped by the sea and moors
- hard-working and straightforward
- historically underappreciated by Westminster
He feels a deep personal connection to the city and says it gave him a sense of home.
What Plymouth needs
His vision for Plymouth is not constitutional theory but practical improvement:
- better leadership
- competent local and national government
- functioning NHS and addiction services
- decent social housing
- public services that actually work
He believes people are tired of politics as spectacle and simply want:
- honesty
- follow-through
- basic competence
Relationships, Contradictions, and Takeaways
Mercer on political figures
He is notably mixed but revealing about major Conservative figures:
- David Cameron: respect for competence and principle
- Theresa May: respect, but she let veterans down
- Boris Johnson: personally frustrating, often dishonest, but Mercer chose to work with him to get veterans policy over the line
- Liz Truss: “reliably stupid” is his blunt summary
The central contradiction in Mercer
The interview keeps returning to a core tension:
- he despises dishonesty and moral weakness
- yet he was willing to work with flawed leaders if it got results for veterans
That tension helps explain both his effectiveness and why he became isolated in Westminster.
Bottom line
Mercer’s view is that Britain does not need flashy constitutional reinvention as much as it needs:
- better people
- better standards
- truthful politics
- a more honest defence strategy
- real service to citizens rather than party game-playing
He comes across as angry, principled, self-aware, and unusually candid — a politician who sees politics as a moral fight, not a career.
