Dame Susan Langley on accidental careers, authentic leadership and opening doors
Dame Susan Langley is the Lady Mayor of the City of London, one of the world’s oldest civic offices, representing the UK’s financial and professional services sector at home and abroad. Through the role, she champions social mobility, authentic leadership and broader access to the City.
Sue’s journey from the East End of London to one of the most historic offices in the world is as improbable as it is inspiring. “Never, ever, ever,” she says, when asked whether she imagined herself in such a role. The idea of living in Mansion House, presiding over centuries-old ceremonies, would have seemed impossibly remote.
And yet, here she is, the 697th holder of an office dating back to 1189, only the third woman to take on the role, and the first to formally adopt the title Lady – not Lord – Mayor.
Before becoming Lady Mayor, Sue (BSc Geography, 1985) built a distinguished career in the financial services sector, particularly in wealth management and private banking. She held senior leadership roles at major institutions, earning a strong reputation for her expertise in global markets and client strategy. Her contributions to financial services and public life were recognised with a damehood in 2024.
A career shaped by curiosity.
Sue describes her professional journey as an “accidental career.” She left Southampton without a clear plan. Instead, she chose to travel, working her way across the world, deliberately seeking roles that would build experience rather than simply fund the next destination. From environmental research to a stint with the stock exchange in Australia, each experience added a layer to her understanding of the world.
When she returned to the UK, she applied for one job. Just one. Every subsequent opportunity came through conversations, introductions and a willingness to explore new directions. A chance encounter with an auditor led her into consulting; a client opened the door to insurance; a conversation in the House of Lords sparked a move into government. Even the path to becoming Lady Mayor began with a question posed years before she accepted, “I laughed,” she admits. “It took them 15 years to persuade me.”
What changed her mind was not prestige or tradition, but impact. The role, she discovered, is far more than ceremonial. While the public sees the pageantry – the red robes and golden carriage, the state banquets, the historic processions – these make up less than five per cent of the job. The rest is about advocacy, diplomacy and influence: championing UK expertise, building international relationships and convening voices to tackle major issues.
Ultimately, it was a conversation with one of her mentees that tipped the balance. “You’re always telling us that to change things, someone has to go first,” the mentee said, “If not you, then who?”. So, Sue decided to stand.
The Southampton effect
If her career has been shaped by chance encounters and bold decisions, its foundation was laid at Southampton. “University was transformational,” she says simply.
Coming from London’s East End, Sue’s early education had been modest. She recalls being taught A Levels in a cleared-out chemistry cupboard. Southampton, by contrast, offered space and encouragement. “It gave me the confidence to be myself,” she explains.
That confidence became the thread running through her career. It enabled her to take risks, to pivot when things didn’t work out, and to trust her instincts in unfamiliar environments.
“Don’t overthink it,” she says. “Be curious. Try things. If something doesn’t work, try something else.” Above all, she champions resilience, “the most underrated word in the English language.”
Her perspective on privilege is equally striking. While some might point to her background as non-traditional, Sue reframes it entirely. “I come from a hugely privileged background,” she says, “because my parents loved me and my teachers encouraged me.”
“Unsquaring” the Square Mile
As Lady Mayor, Sue has chosen to focus much of her energy on social mobility. Her guiding belief is simple: talent is everywhere, but opportunity is not.
Throughout her career she has mentored extensively, particularly supporting those who lack confidence or feel they don’t fit traditional expectations. Now, with the mayor’s platform, she is scaling that work – bringing together organisations, creating access and challenging perceptions of the City.
Such perceptions emerged during a virtual internship she addressed shortly after taking up her year in office. Instead of questions about finance or insurance, students asked whether the City was “scary,” whether they spoke “the right way,” or had attended “the right school.”
Her response was characteristically direct – and, as it turns out, rather memorable. “We need to ‘unsquare the Square Mile,’” she said, coining a phrase that has since become a defining theme of her tenure. The City, she argues, is not a closed square with fixed boundaries, but a dynamic, open ecosystem. “I’m living proof that it doesn’t have boundaries,” she says.
Practical initiatives are already underway. From convening social mobility charities at Mansion House to launching City insight days that invite young people into workplaces, Sue is focused on demystifying the sector and widening access. Sometimes, she notes, the first step is simply showing people that they belong.
Representation, too, plays a powerful role. The impact of her appointment as Lady Mayor became clear during the Lady Mayor’s Show, when droves of young people lined the streets of London to watch the procession. Messages from parents followed: “Our daughter now wants to be Lady Mayor.”
“If I’ve encouraged even a handful of people to do something different,” she says, “that’s what matters.”
Redefining leadership
Sue is refreshingly candid about leadership. “Fantastic! We don’t need more traditional leaders,” she says when asked what advice she would give to those who don’t see themselves fitting the mould.
In her view, leadership is not about conforming to a stereotype, but about vision, authenticity and the ability to bring people with you. Trying to imitate others, she warns, is both exhausting and ineffective. “People can tell when it’s not you,” she says.
Her own approach has been to remain unapologetically herself, even when stepping into one of the most tradition-bound roles in the world. She has challenged conventions, including changing the title to Lady Mayor despite initial resistance. Tradition, she believes, should provide stability but not act as an anchor. “If we’re doing something just because it’s always been done that way,” she says, “maybe it’s time to ask why.”
Authenticity also means acknowledging mistakes. Sue speaks openly about moments when she has had to reverse course or admit she was wrong. Far from undermining credibility, she sees this honesty as a source of trust.
Redefining leadership
As a new graduate, Sue’s idea of success was straightforward: an interesting job, financial independence, perhaps a flat of her own. Today, her definition has evolved.
“Success now is about inspiring others,” she says. While her official responsibilities include promoting the UK internationally – countering misconceptions and highlighting strengths – her personal measure of success lies elsewhere. “What have I done to increase opportunities for others?” she asks. “What have I done to encourage people to believe they can do this too?”
Memories of Southampton
Sue recalls her memories of Southampton with warmth, and a big dose of humour.
There was the RAG week prank that saw her mistaken for a gnome while wearing her favourite brown and yellow dress.
And then there was the surf club.
Drawn in by the sound of The Beach Boys and images of sun-soaked beaches, she signed up for the surf club during Freshers’ Week.
The reality was rather different. On a cold, rainy day in Bournemouth, she struggled into a borrowed wetsuit – only to discover it was inside out – and found herself directed to the end of a pier moments later.
“I don’t think I want to—” she attempted, before being promptly pushed into the sea.
“That was my introduction to surfing,” she laughs. “From Hawaiian sunshine to being shoved off a pier.” Despite this, Sue stayed in the surf club for the duration of her degree, even becoming treasurer in her second year. A testament, perhaps, to the resilience she now champions.
Sue Langley’s tenure as Lady Mayor of the City of London runs until November. We are immensely proud of all she has achieved and look forward to seeing what comes next in her remarkable ‘accidental career’.
