Milo attended a £27,174 a year Westminster School, where he developed a love for sports. In fact, Milo was described as a “delight to watch” and “without doubt the player of the season” in the 2011 issue of his school magazine for his football ability. After this, he studied at the London School of Oriental and African Studies which prompted him to complete a five-month internship at Esquire in the Middle East.

Leading on from his cultural education, Milo is known to speak French, Russian and Arabic – very impressive!
