A modular wall comprising at least two wall panels, each comprising first and second vertical edges, a top edge and a bottom edge. A leg is connectable to a wall panel, configured to apply a vertical force on the wall panel. The first and second vertical edges are shaped to form a male-female connection between adjacent wall panels. Adjacent wall panels are joined together using adhesive. Each vertical edge is provided with cooperating elements, which in use engage with a cooperating element on an adjacent wall panel to pull the two wall panels together whilst the adhesive cures.
