Already underway is a short, focused programme of work to explore realistic options across road, rail and bus interventions. The emphasis is on measures that are practical, deliverable and capable of making a meaningful difference in the near to medium term. This work will draw on the substantial evidence base already available and focus on identifying practical and deliverable options. I will report back to Members on the outcome of this work in Plenary in the autumn term, setting out the Government’s intended way forward. (Saesneg yn unig)
