A method of supporting a tubular within a bore including the steps of at least partially expanding a sleeve into contact with a bore wall to secure the sleeve within the bore, and engaging a portion of the tubular to be supported with the sleeve to provide hanging support for the tubular. In one embodiment, the sleeve is expanded by engagement with the tubular. In another embodiment, the sleeve is initially expanded using a roller expansion tool, with further expansion being achieved by way of engagement of the tubular with the sleeve. An apparatus for supporting a tubular within a bore in one embodiment comprises an expandable sleeve having a first surface and being adapted to be expanded into contact with a bore wall, and a conical portion adapted to be coupled to a tubular, the conical portion having a second surface adapted to engage the first surface of the sleeve.
