I now look forward to continuing a close relationship with David Jones, who I know will do an excellent job in the role of Secretary of State for Wales.
He has been instrumental in delivering for Wales as Minister and is the right choice to take up this position.
I know he will maintain the high levels of determination we have seen for Wales in recent years and I look forward to working with him.
