A method of expanding tubing downhole comprises providing a section of expandable tubing (14) of a first diameter and comprising slots or apertures (16), and axially compressing the tubing to induce buckling, such that the buckled portion describes a larger second diameter. The resulting diametric expansion may be utilised to anchor or seal the tubing within a larger bore.
