Prime Minister Sir Keir Starmer led the tributes, describing Sir Alex as someone who "led an exemplary life and career" and stating "he will be remembered by the many ministers, colleagues, friends and family for his utmost dedication to British public life and protecting our nation."

She noted that Sir Alex "made a lasting and distinctive contribution to our country and indeed to global security".
Before taking charge of MI6, Sir Alex built an extensive career spanning postings across Europe, the Middle East and Afghanistan, having previously served as a British Army officer.
His early intelligence work began in the western Balkans during the mid-1990s, where he contributed to efforts that helped pave the way for war criminals to face prosecution.
Sir Alex subsequently rose to lead MI6's counter-terrorism operations, a role that encompassed security preparations for the London 2012 Olympic Games.
He took over from Sir John Sawers as head of the Secret Intelligence Service in late 2014, bringing with him decades of operational experience across some of the world's most volatile regions.
Throughout his tenure, Sir Alex grappled with the evolving nature of modern espionage, calling in 2018 for a new generation of officers capable of meeting "the threats of the hybrid age" posed by both terrorism and hostile nation states.
During his six years at the helm of MI6, Sir Alex confronted a complex array of security threats and his tenure was extended by a year beyond its planned 2019 conclusion to guide the agency through Brexit.
He became known for his memorable remarks about James Bond, noting in 2016 that the fictional spy would need to "change his ways" to pass MI6's recruitment process, despite having "created a powerful brand" for the service.
In 2017, he disclosed that the real-life equivalent of Q was a woman, part of efforts to attract more female recruits.
