First, may I apologise to the right hon. Gentleman for last week mistakenly believing him to be someone who wanted to break up our United Kingdom? I unreservedly withdraw that aspersion. I know that he and I want to keep our Union together. On the quarantine issue, however, I must say to him that I think it is very sensible for this country to have measures in place to protect our population from vectors of disease coming back into the UK from abroad. That is the right thing to do.
