“When Mongolia’s spy chief stepped off an Aeroflot flight into Heathrow a few weeks ago, he expected a welcome befitting a foreign dignitary arriving for high-level talks with the British government on a new era of intelligence co-operation. After all, preparations for his visit had included an invitation to meet Downing Street’s National Security Adviser.
But rather than being ushered through Heathrow’s VIP lounge for talks in Whitehall’s inner sanctum, the chief executive of Mongolia’s National Security Council and the one-time head of its security service was met by Scotland Yard detectives armed with an international warrant for his arrest.”
