The present invention relates to a downhole expandable tubular for expansion in a well downhole from a first outer diameter to a second outer diameter to abut against an inner face of a well tubular metal structure or borehole, the downhole expandable tubular having an outer face, a longitudinal extension and a tubular length along the longitudinal extension. The invention also relates to an annular barrier for expansion in an annulus between a well tubular metal structure and an inner face of a borehole or another well tubular metal structure for providing zone isolation between a first zone and a second zone of the borehole. Moreover, the invention relates to a downhole system comprising a well tubular metal structure having an inner face, an outer face, a downhole expandable tubular being connected to the inner face, and a downhole closure unit arranged on the outer face for permanently sealing off a control line controlling a well component of the well tubular metal structure prior to plug and abandonment of a well having a top. Finally, the invention relates to a method of permanently closing fluid communication in the downhole closure unit for permanently sealing off a control line prior to plug and abandonment of a well.
