As the Member of Parliament whose constituency includes the Wrightbus factory, which has carried out pioneering work—it was the first to produce the hydrogen bus for the UK and the battery diesel bus—I have been pushing the Prime Minister on this for some time. I welcome the statement and the plans to buy British-made buses, but there are many shovel-ready projects available for zero-emission buses across the UK. Under the current plans, the roll-out will not be until 2022? What are we waiting for? Why cannot we get on with it? I hope that the Secretary of State will tell his officials that they have a mission to get this money out the door, to get it into shovel-ready projects, and to buy British buses without any further delay.
