A disc for use in an axial flow turbomachine having a main flow annulus which includes an inner flow boundary defined by axially adjacent stator vane and rotor blade platform sections. The disc comprises an axially extending sealing member which extends from its radially outer periphery to bridge the gap between adjacent rotor blade and stator vane platform sections. The sealing member is formed integrally with the disc. The arrangement minimises the unsealed stator well region between the rotatable and non-rotatable platforms and thereby provides for improved operational flow stability.
