英国情报机构MI6在法国杂志《快报》组织的同行评审中被列为欧洲最强的外国情报部门[1]。评审邀请来自25个国家的60名专业人士进行评估，MI6获得251分的最高分，领先法国情报机构DGSE的169分[1]。
MI6因在招募高层告密者以及渗透俄罗斯、中国、伊朗和土耳其权力精英方面获得赞誉[1]。前CIA欧洲和欧亚地区行动主管Ralph Goff表示："英国人在乌克兰问题上处于领先地位。我们紧跟其后。"[1]前CIA驻站主任Robert Gorelick也评价道："英国拥有迄今为止欧洲最强大的秘密部队。MI6是非凡的。"[1]
英国曾是第一个向乌克兰警告俄罗斯入侵可能性的国家，该入侵始于2022年2月[1]。2023年，Blaise Metreweli成为首位女性MI6领导人，接替Richard Moore爵士担任该职务[1]。
Britain's MI6 has been ranked as Europe's leading foreign intelligence agency in a peer review assessment, scoring 251 points and significantly outpacing its continental counterparts [1]. The evaluation, conducted by French magazine L'Express, brought together 60 intelligence professionals from 25 countries to assess Western allied intelligence services [1]. France's DGSE came in second place with 169 points [1].
MI6 earned particular praise for its effectiveness in recruiting high-level informants and penetrating the inner circles of power in Russia, China, Iran, and Turkey [1]. Former CIA European and Eurasian operations chief Ralph Goff commented that "the British are ahead on Ukraine. We are catching up," while former CIA station chief Robert Gorelick stated that "the British have by far the strongest secret service in Europe. MI6 is extraordinary" [1].
The agency's prominence was further underscored by Britain's role as the first country to warn Ukraine of the imminent Russian invasion, which began in February 2022 [1]. In 2023, Blaise Metreweli became MI6's first female leader, succeeding Sir Richard Moore [1].
