It is one of the assumptions of most of the eurosceptic wing that as far as possible (allowing for international agreements and so on) legislation and regulation in this country should be carried out by our elected representatives within certain constitutional boundaries, which, in my opinion, includes a role for the House of Lords, chosen on a completely different basis and one for and independent judiciary. MPs must, in that system, be of huge importance.
Nothing wrong with that, you might say. After all, MPs can always be voted out (though many people who live in safe constituencies might disagree with that); they can be challenged while they are sitting though I dislike the idea of recall as we do vote for our MPs as members of parties and a recall can so easily degenerate into one particular group re-fighting a perfectly valid election. Anyway, there we are: MPs rather than the various levels of eurocracy.
Then we get the spectacle that is going on in the Commons right now: a debate on whether Donald Trump, an American businessman and a candidate for the Presidential nomination, should be excluded from the United Kingdom. Why? Well, he said a few things we do not like or some of us do not like and, in any way, his behaviour is boorish. Not only are those not reasons for excluding someone from this country but it is an obvious waste of time for MPs even to debate it.
Now admittedly, this is not happening in the Chamber but in Westminster Hall. It is, nevertheless, taking up a great deal of Parliamentary time. The debate is taking place at the instigation of the Petitions Committee, which has had to deal with two e-petitions, 114003, with 500,000 signatures that is in favour of the ban and 114907 with 40,000 signatures that is against it. In neither case are the numbers big enough to make it a matter for Parliamentary debate.
As it happens, the Home Secretary has the powers to exclude people from entering the country and this power has been exercised at various times - some of those we know about, many we do not but we must assume that the reasons had to be more than just unpleasant and boorish behaviour.
Let me just add that so far as anyone knows no UK variant of the US Magnitsky Act with its list of people who were responsible for the torture and death of the lawyer Sergei Magnitsky who had been employed by a British firm exists.
