An annulus filler for installation between blades, such as fan blades, of the rotor of a gas turbine engine comprises a channel 13 which accommodates a post 6 defined between blade slots 4 of the disc 2. A chocking surface 24 of the annulus filler 12 contacts regions of a contact surface 26 of the post 6 to chock the head 10 of the post 6 within the channel 30. The annulus filler 12 is thus supported along the axial length of the post 6, enabling it to withstand circumferential forces generated on rotation of the disc 2.
