A leaf seal assembly' is disclosed for use in a gap between a rotating componentand a stationary component, for example of a turbo-machine. The leaf seal assemblycomprises at least one leaf sealhaving a generally planar surface. A runneris coupled to a distal end of the least one leaf seal. The at least one leaf sealmaintains the runner′ in a first position away from the rotating componentin an unpressurised inoperative state. The runnermoves to a second position, close to, but not contacting, the rotating componentin a pressurised operative state. In some embodiments the at least one leaf seal is angled in the direction of the flow. In some embodiments a first leaf seal is vented. In some embodiments the leaf seal assembly is segmented.
