Michael is a South Africa-born fashion tycoon said to be worth £80million. He owns a £19 million mansion in central London, as well as his home in South Africa’s capital.
The 62-year-old comes from a wealthy family thanks to his grandfather founding a furniture retailer in the 1930s, which Michael's father, Stanley Lewis, leveraged to buy a stake in clothing retailer Foschini Group in the 1980s. Michael later took a place on the Foschini Group board and has been chairing it since 2015.

What has Lady Kitty Spencer said about Michael Lewis?
Kitty has remained tight-lipped about her relationship but has spoken about the importance of love in the past.
She previously told Town & Country magazine: "It's not that I don't place an importance on love. It's because, for me, love is the most important thing in the world, and I will protect it with all my heart by not making it a topic of discussion.
"You open yourself up to other people having opinions, and it just isn't relevant to anybody's life but mine and my family's."
Kitty added: "I just look forward to a really happy home life: a happy marriage and happy children. And I feel very at peace that things play out the way they should."
