I'm delighted on this occasion we've managed to send this person off to a country where he will face justice.
Now we should learn every lesson.How do we stop these people coming in? How do we get rid of them more quickly? How do we make sure they don't spend so long at taxpayers' expense?
I'm as frustrated as the rest of the country when these things happen.
I'm delighted that this man at least is on an airplane and on his way to face justice.
