Fiscal Responsibility Bill

On the question of duties, does my hon. Friend agree that the point he is making could equally be applied to the Government Departments on which Parliament has imposed a series of duties that drive levels of public expenditure ever upwards? Does he not agree that, to get the whole question of public expenditure right, we would have to amend or repeal many of the duties imposed on public bodies in order to reduce the overall level of public expenditure?
