Pc Wayne Couzens, of the London force, pleaded guilty to the kidnap and rape of Ms Everard at the Old Bailey this morning (Tuesday).
Asked how he pleaded to the charge of rape, Couzens again replied: "Guilty, sir".
Mr Couzens, a police constable whose primary role at the time was uniformed patrol duties of diplomatic premises, was arrested in Kent, England and charged with her kidnap and murder.
The court heard Couzens accepted responsibility for the killing of Ms Everard but was not asked to enter a plea to a charge of murder while medical reports are ongoing.
The 33-year-old marketing executive, disappeared while walking home in south London in March and was later discovered more than 50 miles away in Great Chart, near Ashford. The last known sighting of her was from someone's doorbell footage, showing her walking alone at around 9.30pm.
The phrase "she was just walking home" began to trend on social media after her disappearance, with masses of women sharing their horror and outrage at what had happened, as well as the precautionary measures they constantly take in order to feel safe.
"Count three, the count of murder, has not been put to the defendant because medical reports are awaited in relation to that allegation - although the defendant accepts responsibility for the killing".
Members of Ms Everard's family sat in court to witness the defendant enter his pleas.
A postmortem said that she died from compression on her neck.
During March the Metropolitan Police swarmed into Kent yo search Couzens' home, the area where the body was found and his former workplace, the now abandoned BCB Garage in Centre Road, Dover.
A vigil in memory of Ms Everard ended in ugly scenes when the police moved in to break up a large gathering that was in breach of lockdown restrictions.
