The present invention provides a running toolfor a casing hangerin which the casing hangeris arranged to be clamped within a well bore. In the clamped position, the suspension weight of the casing hanger(and suspended) casing string is supported by the wellhead and the running toolis then releasable from the casing hanger. The release of the running toolfrom the casing hangeris performed by applying an axial pressure down the running toolwhich then enables the securement meansof the running toolto be moved into an unsecured position. In the secured position, the casing hangeris suspendable from the running tooland the running toolsupports the suspension weight of the casing hanger(and the casing string located there below). The running toolcomprises activation meansin order to enable the securement meansto move from the secured position to the unsecured position. The running toolincludes release prevention meansin order to prevent the movement of the securement meansfrom the secured position to the unsecured position whilst the suspension weight of the casing hangeris suspended from the running tool
