These are the 9 British universities that produce the most CEOs

It takes grit and determination to run a business, not a degree from Oxford University or the London School of Economics.

Emolument.com, the crowdsourced pay-data website, analysed data from 26,000 former students to find the universities with the highest ratio of graduates to chief executives, chief technology officers, or partners.

The company found that the bigger and older UK universities don't produce as many business leaders as most people would think.

Emolument found that "alumni from Sheffield, Brunel or Leicester University are less likely to be wooed by big banks or consultancies than their Oxbridge counterparts," the company said.

"And therefore more eager launch their own business or joining budding start-ups, thereby climbing through the ranks more quickly and reaching leadership positions in smaller, more nimble structures," Emolument said.

Here's the list of the unis with the highest percentages of business leaders in their alumni ranks.
