C lelia Haji-Ioannou is a Cypriot billionaire and a member of one of the country's wealthiest families. She is the daughter of the late Loucas Haji-Ioannou, a Greek-Cypriot shipping magnate who built a massive fleet of oil tankers. Upon his death, his fortune was divided among his three children: Clelia, her brother Polys, and her brother Stelios, the famous founder of the budget airline easyJet.

While her brother Stelios is the high-profile entrepreneur of the family, Clelia's wealth is primarily derived from her inherited stake in the family's assets. She holds a large portfolio of real estate, particularly in Monaco and London, and also owns a significant stake in her brother's airline, easyJet. She is known for being very private and focuses on managing her extensive property and investment portfolio. She is also a philanthropist through her own foundation.
