In 2014, one of the oldest financial institutions in the City of London, Lloyd's, appointed its first ever female chief executive, Inga Beale. Next year, she will step down from the role.

A champion for diversity in the workplace, Beale has overseen big cultural and technological changes at the insurance market - some controversial. A drinking ban for Lloyd's employees during working hours made the headlines in 2017, as did a loosening of the famously conservative dress code.

She has faced other challenges during her leadership, notably Brexit and a "disastrous" 2017, which was one of the worst ever years for natural disasters globally. Big insurance pay-outs led to Lloyd's reporting a £2bn loss that year.

Inga Beale, one of the UK's few openly bisexual senior business leaders, did not follow a typical route to the top. She dropped out of financial services for a year to go back-packing in Asia and Australia, and is a former competitive rugby player.
