I believe HS2 is vital to the growth of the UK economy and will deliver the capacity our rail network sorely needs. Sir David is the right man to continue the delivery of this project.
I am delighted at his appointment and am confident that alongside Alison Munro our Chief Executive he will continue to drive the scheme forward.
I am proud of all that I have achieved, particularly that we will be bringing the Hybrid Bill to Parliament by the end of the year, after which I will be standing down.
I am pleased to have been able to play a key role in delivering this project which will serve the country for many generations to come.
