I want to follow up what my hon. Friend the Member for Cities of London and Westminster (Mr. Field) said, and in particular his phrase ''the two sovereign Parliaments''. I am perplexed by the question of which Parliament is meant to be sovereign. We are told that under the Sewel motion, Ministers in Westminster are making law for the Scots on their behalf, and are changing the word ''may'' to the word ''must'' for them. If I understood correctly the Minister's answer to the good question asked by the hon. Member for Orkney and Shetland, the Scots can, if they choose, change it back. Ministers may point out that there is no appetite for such a change, and say that no one in the Scottish Parliament wants to return discretion to the courts, but that they want to impose the mandatory procedure and follow the draconian approach to life that the hon. Member for Glasgow, Pollok continually advocates.
