For more than a decade Gabby Bertin was one of the powerful women by David Camerons side, an invisible yet hugely influential figure around Westminster and Whitehall.
In September 2016, Gabby became the youngest member of the House of Lords. At just 41, she stands out in a chamber where the average age is 70. She recently sponsored the Stalking Protection Bill during its passage into the Lords, to crack down on stalking by strangers.
Baroness Bertin is currently director of strategic communications and campaigns at BT.
