On 7 March 2018 and on 14 March 2018 two notices were issued to protect MI6 in relation to some aspects of the Skripal affair. In the early 1990s Sergei Skripal was recruited by Pablo Miller, the MI6 agent inside the UK embassy to Estonia in Tallinn. The MI6 officer under diplomatic cover in Moscow at this time was Christopher Steele. Miller was also the handler of Skripal after he went to jail and was released by Russia in a spy swap. Both lived in Salisbury. Steele and Miller worked for Orbis Business Intelligence which compiled the controversial Trump–Russia dossier, comprising 17 memos written in 2016 alleging misconduct and conspiracy between Donald Trump's presidential campaign and the Putin administration. While the precise nature of the relations between Skripal, Miller, and Steele were hidden, enough was already known to raise questions about Skripal's ongoing involvement with British intelligence.
