Badenoch hasn’t had the super-privileged typical-Tory, public school followed by Oxbridge upbringing so those (silly) arguments aren’t really applicable here anyway.
Her parents are well-educated medical field professionals in Nigeria but she was sent to London alone at just 16.
(don’t worry, I realise they aren’t your arguments, SirNeigh!)
from Wikipedia:
Olukemi Olufunto Adegoke was born on 2 January 1980 in Wimbledon, London.
She is the daughter of Femi Adegboke and Feyi Adegoke who are of Nigerian origin. Her father was a GP and her mother is a professor of physiology. Badenoch's childhood included living in Lagos, Nigeria and in the United States, where her mother lectured.
She has a brother named Fola and a sister called Lola.
She returned to the UK at the age of 16 to live with a friend of her mother's owing to the deteriorating political and economic situation in Nigeria which had affected her family.
Although a British citizen and born in the UK, Badenoch stated that she was “to all intents and purposes a first-generation immigrant” during her parliamentary maiden speech.
She obtained A Levels from Phoenix College, a former further education college in Morden, whilst working at a branch of McDonald's among other jobs.
Badenoch studied Computer Systems Engineering at the University of Sussex, completing an Master of Engineering (MEng) degree in 2003.
She initially worked within the IT sector, first as a software engineer at Logica (later CGI Group) from 2003 to 2006.
While working there she studied law part-time at Birkbeck, University of London, and completed an Bachelor of Laws (LLB) degree in 2009.
Badenoch then worked as a systems analyst at the Royal Bank of Scotland Group before pursuing a career in consultancy and financial services, working as an associate director of private bank and wealth manager Coutts from 2006 to 2013 and later a digital director at The Spectator from 2015 to 2016.
