a needle configured to move between a retracted position and an inserted position;
an insertion mechanism configured to move the needle from the retracted position to the inserted position when activated;
a locking arm which, in a locked position, is engaged with the insertion mechanism to prevent activation of the insertion mechanism and, in an unlocked position, is disengaged from the insertion mechanism;
a retraction mechanism configured to move the needle from the inserted position to the retracted position when activated; and
a trigger configured to move between a disengaged position and an engaged position,
wherein the trigger is arranged to be moved from the disengaged position to the engaged position when the medicament delivery device is placed on a body of a patient, and on moving from the disengaged position to the engaged position, the trigger is configured to move the locking arm from the locked position to the unlocked position, and
wherein, on moving from the engaged position to the disengaged position, the trigger is configured to activate the retraction mechanism.
