I thank my hon. Friend for keeping the House updated on that important development.
The key point is that it is clear from the text of the European convention—I have referred to paragraph 2 of article 8—that, under the terms expressly set down by the architects of the convention, the new clause is proportionate. It is proportionate because it applies only to serious criminals who have been imprisoned for a year or more. It therefore ought to withstand any appeal to Strasbourg.
I remind the House that we are not entirely sure how any litigation in Strasbourg on this issue would pan out, whether on the basis of the Bill or the new clause. That is partly because the 47-member-state Council of Europe, to which the Strasbourg Court is accountable, has made two recent declarations in Izmir and Brighton calling on Strasbourg in unequivocal language to meddle less in immigration cases. We therefore have every reason to believe that we will have a greater margin of appreciation in future. I pay tribute to the Minister without Portfolio, my right hon. and learned Friend the Member for Rushcliffe (Mr Clarke), for the efforts that he made when he was Justice Secretary to achieve those resolutions, which have paved the way for the new clause.
