If your cistern is the type with buttons in the centre to depress for flushing then it may remove like mine, which is a Sottini. Pull out the two flushing buttons from their recess. This will expose a screw head which should be unscrewed. The chamber holding the flushing buttons may then be removed and it will allow removal of the entire cistern lid.
