As the number of exoplanet detections is increasing it is becoming clearer that systems with multiple planets are common. The interactions between multiple planets and their parent disc are much more dynamic and complex than those between a single planet and the disc. We perform two-dimensional hydrodynamical simulations to explore the evolution of T Tauri discs which have multiple planets embedded in them. We present preliminary results on the disc structures, the flow of material and the gap properties that are present as a consequence of the presence of multiple planets. If the disc structures are long-lived and can persist for long periods of time, they may well be features that can be observed with new spatially-resolved disc observations.
