Operation Kenova is an ongoing criminal investigation into whether the Royal Ulster Constabulary in Northern Ireland failed to investigate as many as 18 murders in order to protect a high-level double agent codenamed Stakeknife who worked for the Force Research Unit, while at the same time he was deeply embedded and trusted within the Provisional Irish Republican Army (IRA). The investigation started in 2017, headed by Jon Boutcher the former Chief Constable of Bedfordshire Police until his appointment as Chief Constable of the Police Service of Northern Ireland in 2023. It is now led by Iain Livingstone, former Chief Constable of Police Scotland.
