The eldest son of legendary hotel tycoon PV Doyle, Michael sold most of his stake in the family business for around 29m in 1995, netting another 22m from the rest of his shares. He has invested in property. When PV Doyle's widow, who inherited her husband's estate in 1988, died, she left more than 31m to family members, charities and religious organisations. Doyle left 3m to her eldest son Michael and 2m to her son David. The Doyle Collection hotel chain now comprises eight hotels including the Westbury in Dublin and the Kensington in London.
