And since she is openly bi-sexual, she uses her position of power to lobby for equality for the lesbian, gay, bisexual, and transgender (LGBT) community in the workplace.
On Friday, she told delegates at the Stonewall workplace conference today that LGBT inclusion is "still a work in progress" in Britain.
However, there are a number of other LGBT executives that OUTstanding, the networking group, consider as incredibly power and are poised to make a difference in the corporate world.
OUTstanding lists 100 people who it thinks challenges the presumption that you can't be openly LGBT and be successful in business.
"Those featured are an inspiration to anyone who fears that they may have to be closeted at work, and waste valuable effort muting their authentic selves," said Suki Sandhu, chief executive of OUTstanding.
However, notably Apple's CEO Tim Cook was missing. OUTstanding said that it was forced to omit him because it was unable to gain permission for him to be included in the list.
