How did a junior Chinese civil servant who arrived in Britain to do a master’s degree at York University end up as such a close confidant of the Duke of York that he was described as “the very top of the tree” by the prince’s adviser?
Yang Tengbo, 50, also known as Christopher Yang, was able to move in the highest circles of the British establishment. He was invited to Prince Andrew’s 60th birthday party at Royal Lodge, in Windsor, joined visits to St James’s Palace and Windsor Castle, attended a Chinese new year celebration at Downing Street with David Cameron and was pictured in black tie alongside Theresa May and her husband, Philip.
