Passenger Railway Services (Public Ownership) Bill

My Lords, I have one very brief question for the Minister, following the warnings by the noble Lord, Lord Young. Have the Government looked at this from the point of view not just of what I would call the finished product of the nationalised railway system but of how the categorisation of a mixed economy would work? We, the nation, will be in a situation of a mixed, some-and-some economy for a significant number of years to come.
