1. A medicament delivery device comprising:
a body comprising a proximal end and a distal end defining a longitudinal axis;
a needle for injecting medicament;
an actuation member moveable relative to the body along the longitudinal axis for actuating the medicament delivery device;
a lock ring configured to rotate relative to the body about the longitudinal axis between a first position in which the actuation member is not permitted to move along the longitudinal axis relative to the body, and a second position in which the actuation member is permitted to move along the longitudinal axis relative to the body; and
a cap arrangeable in a capped position in which the cap abuts with and conceals the distal end of the body to conceal the needle;
wherein the medicament delivery device is configured such that (i) when the cap is in the capped position, the lock ring is in a first state in which the lock ring is in the first position and is not permitted to rotate towards the second position, and (ii) moving the cap in a distal direction away from the distal end of the body along the longitudinal axis away from the capped position causes the lock ring to be in a second state in which the lock ring is permitted to rotate from the first position towards the second position.
