Rishi Sunak, the UK's new prime minister, points to his time in the US studying and working as a defining part of his life. So what are his American connections?
The 42-year-old has made the California chapter of his biography a key part of his public persona.
He frequently cites his time there in his 20s and early 30s to burnish his credentials as a business-savvy leader.
"I have lived and worked in California and I actually think it's one of the reasons that I would be good at this job," he told the BBC's Laura Kuenssberg last month while running for the Conservative leadership.
"Because what I will bring to this job is a way of thinking that is different. When we think about growth and in a modern economy, how do you drive growth - you drive it through innovation. Because of my experience I know how to build that type of economy."

Here's a closer look at this period which had such an impact on him.
Mr Sunak started his years in America at Stanford University's Graduate School of Business as a Fulbright Scholar, heading to Silicon Valley in 2004 as the internet boom was under way.
The programme, which admits roughly 400 students per year, has a reputation as the most exclusive business degree in the country.
Among the classes Mr Sunak took was "The Paths to Power", intended to help students understand power and how to wield it effectively.
He did not earn any particular academic distinctions and his professor in that class was unable to recollect him - understandably, given he taught 100 students a year.
But a more life-changing landmark in those early US years occurred when he met his wife, Akshata Murty, daughter of the founder of Indian tech firm Infosys.
Classmates at the time have told biographer Michael Ashcroft that they were a "power couple" on campus.
Derrick Bolton, who was assistant dean of admissions from 2001-2016 and remains friendly with the couple, says Mr Sunak entered the programme "very self-assured".
"He knew from a young age that he wanted to make an impact on as many people as possible."
Earlier this summer the couple invited Mr Bolton to Downing Street for tea, where they lived in Mr Sunak's capacity as chancellor. They showed their visitor exhibits on former chancellors and served biscuits marking the Queen's Jubilee.
Mr Bolton, who attended their New York wedding celebration in 2009, said he was surprised they made the time.
"Despite the lofty titles and significant responsibility, they are the same two lovely people they were as students - open and kind and humble and remarkably self-effacing," he said. "They're very low-key, very chill."
After graduating, Mr Sunak took a lucrative job at the London-based hedge fund, TCI Fund Management.
Mr Sunak focused on the US, participating in the firm's bitter 2008 fight with the leaders of America's CSX freight railroad.
Lawyer Marc Weingarten, who worked closely with Mr Sunak at this point, said he stood out as a "sponge for information".
