Former Admiral Sir Ben Key, the erstwhile head of the Royal Navy, has been formally dismissed from service following an investigation into allegations of misconduct, the UK Ministry of Defence (MoD) confirmed. The ministry said Sir Ben’s behaviour had “fallen far short of the values and standards expected of service personnel.”
Sir Ben, 59, acknowledged the decision in a statement, expressing deep regret for his actions. “I deeply regret my conduct in the spring of last year, which fell well below the standard I set for myself and that which I set for the Royal Navy,” he said. He also offered an apology to those personally affected and thanked his wife, family, and friends for their support during what he described as “a very difficult time.”
Sir Ben was removed from duties in May 2025 amid an investigation into an alleged inappropriate relationship with a more junior female colleague. The allegations first surfaced in UK media reports last year, prompting a formal inquiry by military authorities. Relationships of this nature are considered contrary to the military’s code of conduct due to concerns about power imbalances and professionalism.
Chief of Defence Staff Admiral Sir Tony Radakin emphasized that military standards apply equally, regardless of rank. “We expect the highest standards of behaviour from our service personnel and our civil servants. We investigate all allegations of inappropriate behaviour and will take robust action against anyone found to have fallen short of our standards,” he said.
Although Sir Ben retains his knighthood and pension, he has been stripped of his military commission, an uncommon step for an officer of his rank. Traditionally, senior officers retain honorary military titles after retirement, but this will not apply in Sir Ben’s case.
Sir Ben Key joined the Royal Navy as a university cadet in 1984, later qualifying as helicopter aircrew and a principal warfare officer. He served aboard several frigates and destroyers in operational theatres worldwide. He was appointed First Sea Lord in November 2021 and was previously honoured as a Commander of the British Empire (CBE) in 2016 and a Knight Commander of the Order of the Bath (KCB) in 2021.
He has now been succeeded by General Sir Gwyn Jenkins of the Royal Marines.
