The announcement that General Sir Patrick Sanders, former head of the British Army, is to lead Santander’s defence lending division might, at first glance, look like a logical next step for a man steeped in matters of national security. After all, who better to advise a bank on the risks and opportunities of defence investment than someone who has commanded troops, chaired strategic committees, and liaised with industry partners at the highest level?
Yet beneath this appointment lies a question that many in the UK’s political classes have been reluctant to confront: when do the career trajectories of former British generals into corporate boardrooms become not expertise shared, but potential conflicts of interest entrenched?
Sanders, who served as Chief of the General Staff from 2022 to 2024, will now help Santander expand its lending to arms manufacturers. This comes amid what the bank calls a “new era” of defence investment, as NATO states increase military spending and as environmental, social, and governance (ESG) restrictions on arms financing are being quietly relaxed.
Santander’s move is part of a broader trend: financial institutions that once shied away from the defence sector are now rebranding weapons as “essential security assets.”
It’s such a boom time in the military-industrial complex that generals are becoming bankers. We await the first four-star general bitcoin investor.
But for a former head of the British Army to play a role in facilitating this financial shift raises serious ethical questions. During his tenure, Sanders oversaw procurement strategies and industrial partnerships worth billions. The boundaries between his public service and his new private interests are, at the very least, blurred. Will his insider understanding of the Ministry of Defence’s priorities and contacts now give Santander a privileged position in the rapidly expanding defence credit market?
The appointment also sits uneasily alongside a wider pattern that AOAV has long documented: the steady erosion of distance between the UK’s defence establishment and the arms trade. Our research has shown that 86% of senior British defence officials move into private sector defence roles within two years of leaving office. Some go to manufacturers, others to advisory consultancies, and now, increasingly, to financial institutions eager to underwrite the business of war.
The problem is not simply one of perception. When those who once shaped defence policy now profit from its expansion, public trust is inevitably eroded. Sanders’s appointment suggests a revolving door so wide that it has become a corridor, through which influence flows in both directions. Banks gain prestige and access; generals gain pay and position; and the line between national security and corporate security becomes ever harder to see.
This is not a new story. General Sir Nick Carter, Sanders’s predecessor as Chief of the Defence Staff, now advises Israeli arms firms through Exigent Capital, a Jerusalem-based finance company. Ben Wallace, former Defence Secretary, has taken up advisory roles in Saudi Arabia’s security sector. Such transitions have become routine, almost unremarkable.
Though they should be anything but.
When the architects of Britain’s foreign and defence policy go on to advise or profit from those supplying arms to nations accused of human rights abuses, the question is not whether this is technically permissible, but whether it is morally defensible.
Defenders of these appointments will argue that such figures bring invaluable insight into risk assessment and procurement. Yet the opposite may also be true. When financial institutions rely on former military leaders to guide their defence portfolios, they risk importing not objectivity but bias; an embedded worldview that sees military expansion as both inevitable and beneficial. That may be profitable for shareholders. It is less obviously good for democratic oversight.
The Advisory Committee on Business Appointments (ACOBA), Britain’s nominal watchdog for such moves, will almost certainly review Sanders’s case. Yet ACOBA’s record inspires little confidence. It has no enforcement powers, its guidance is often ignored, and its deliberations are largely opaque. In effect, the British system relies on personal honour and public apathy to police conflicts of interest at the highest levels of power. Neither has proved reliable.
Sanders’s move to Santander thus highlights a deeper failure of governance. Britain’s defence establishment, its arms industry, and now its financial institutions are increasingly intertwined in a web of mutual convenience. As one senior banker told City AM, “Supporting this sector is critical for the security of the region.” But whose security, precisely? For many civilians in Gaza, Yemen, or Ukraine, the British-financed defence industry has meant destruction, not protection.
The revolving door between generals and bankers is not, in itself, evidence of wrongdoing. Yet it does reveal how the boundaries between public service and private profit are dissolving in plain sight. When military leadership becomes a stepping-stone to corporate lobbying and financial influence, the moral authority of the armed forces, already under strain, risks being further diminished.
If Britain wishes to preserve integrity in its defence policy, it must impose stricter post-service restrictions on senior officials, expand ACOBA’s powers, and demand full transparency from those who profit from their former roles.
Until then, every such appointment will raise the same uncomfortable questions about how they are presented in the future in the media and in politics: as former generals or as financial lobbyists?
