Scotland Bill

On taxation generally, is not the lesson that we have learned, from the original Scotland Act 1998, through many Standing Orders over two Parliaments, that we are involved in an iterative process? What can be devolved should be devolved, but at a gentle pace, so that we can assimilate what has happened. In that regard, the agreement that the three parties have come to is the correct way to proceed at this time, but does not preclude further devolution when appropriate at a later stage.
