I am grateful to my hon. Friend. He has anticipated a point that I shall be making later if time permits.
There has been a suggestion that there is limited evidence of fraud, and some Opposition Members have suggested that there is no such evidence. I remind the House that last year I took a random sample of 100 people who had been to my constituency seeking leave to remain, and who had absolutely no right to vote in this country. Of those people, 21 were on the electoral roll. I repeated the exercise this year, and it produced a similar result.
