Farr worked for the Secret Intelligence Service in Afghanistan in the 1980s, in southern Africa and the Middle East. Farr was MI6's director of security and public affairs at the time of his appointment to the OSCT by John Reid, then Home Secretary, in the wake of the 2006 transatlantic aircraft plot. This role made him the senior government official responsible for counter terrorist and organised crime strategy. In 2010 Farr was the recipient of a strategic briefing paper from the Quilliamthink tank, the paper being a confidential review of the British government's anti-terrorism Prevent strategy. The paper was "particularly critical of the view that government partnerships with non-violent yet otherwise extreme Islamists were the best way to fend off Jihadism." The report provoked protests from various groups which had been identified in the Quilliam briefing as sympathetic or supportive of Islamist extremism, and was described as "McCarthyite" by Inayat Bunglawala, chairman of Muslims4Uk and Fatima Khan, vice-chair of the Muslim Safety Forum. Bunglawala added: "In effect, Quilliam – a body funded very generously by the government through Prevent – are attempting to set themselves up as arbiters of who is and is not an acceptable Muslim." A Home Office spokesman told the press that the report had not been solicited but added: "We believe the Prevent programme isn't working as effectively as it could and want a strategy that is effective and properly focused – that is why we are reviewing it." Farr has been described as a "key figure" behind the operation of control orders and 'TPIM notices', their successors. Farr was passed over for the role of head of MI6, he also failed to be appointed Permanent Secretary at the Home Office. The Guardian reported that several officials at the Home Office threatened to resign if Farr were promoted to the top job. Farr was responsible for the Prevent anti-terrorism strategy, the Interception Modernisation Programme under Labour and the current Communications Capabilities Development Programme, both being projects to enable to the government to surveil the traffic data of ordinary Internet communications of UK citizens. The programme has resulted in the draft Communications Data Bill 2012. During the 2012 Summer Olympics in London, Farr was in charge of security, where he was behind the siting of missiles on the roofs of residential buildings in East London. The Financial Times reported in April 2014 that Farr was one of three people shortlisted for the role of Director of the Government Communications Headquarters. In May 2014, Farr made a witness statement on behalf of the government and the three main intelligence agencies for the Investigatory Powers Tribunal, in a legal case brought by advocacy groups including Privacy International, Liberty and Amnesty International, explaining the legal basis for the interception of electronic communications under the Regulation of Investigatory Powers Act 2000. This was characterised in the media as an explanation of how the security services can legally monitor "Facebook, Google and Twitter" usage by UK citizens. In June 2014, there was a very public argument between the Home Office and Department for Education about alleged extremism in Birmingham schools. The Prime Minister David Cameroned intervened and forced Education Secretary Michael Gove to apologise to Farr for briefings critical of him which appeared on the front page of The Times. On 23 November 2015, Farr was announced as the next Chair of the Joint Intelligence Committee. The JIC is part of the Cabinet Office.
Personality
In a profile of Farr, The Guardian newspaper said that: The director of national security and resilience at the Royal United Services Institute, Charlie Edwards, said that Farr is "...not just an effective operator in the field, he is one of the most committed civil servants you will come across... Yes, he is robust, but first and foremost he is fair and most importantly he gets the job done." Shami Chakrabarti, the director of the civil libertiesadvocacy organisation Liberty, described Farr as "...the only person ever to shout at me in the Home Office. I prefer awesome power to be wielded by humbler hands and officials to be both civil and servants."
