Marlborough College is the latest well-known independent school to open an outpost in Asia.
Some 350 children are set to begin their first term at Marlborough College Malaysia on Monday.
The Wiltshire-based school joins the likes of Dulwich College, Harrow and Wellington College in the international school market.
Private schools, like universities, often use overseas outposts to fund bursaries and lower fees in the UK.
Speaking in advance of the launch, master of Marlborough Jonathan Leigh, described the move as a “significant expansion of one of England’s finest schools”.
