My Lords, this part of the Bill concerning Members of Parliament is a hugely important and grave issue, but I think it is probably about right now. As the House and the Minister will know, when the legislation went through the other place, there was a change. Instead of the Prime Minister being informed about a Member of Parliament or of this House having a warrant against them, now the Prime Minister must approve such a warrant. I think that is absolutely right.
There are a couple of points worth making. I agree with the noble Lord, Lord Beith, that the idea of the Speaker of the House of Commons being involved is a very difficult precedent to set, not only because it puts a great burden on the Speaker but because this part of the Bill refers not just to the British Parliament—both this House and the other place—but to the Welsh Assembly, the Northern Ireland Assembly, the Scottish Parliament and, for the time being at least, the European Parliament. If the Speaker was to be involved, surely it would be necessary for the Presiding Officers of those parliaments and assemblies also to be. Frankly, that it is something that they would not particularly welcome.
With regard to the point made about the First Minister of Scotland, that same argument applies. If you say that the First Minister of Scotland ought to be involved, surely the First Minister of Wales would have to be involved and, presumably, the First and Deputy First Ministers of Northern Ireland as well—not to mention, for the time being, the President of the European Parliament. I am not sure that would work. Nevertheless, it is important that such matters are raised.
Finally, is the Wilson doctrine obsolete as a consequence of the legislation? Will it be replaced by what is now in the Bill, or does the Wilson doctrine still stand in the sense that it has always referred to a change of policy, rather than to individual people—
Members of the House of Commons or whoever—who might be subject to interception? I would be grateful to the Minister if he said, when he responds, whether the Wilson doctrine is now finally dead and buried.
