Can we return to the subject of converting the venues please. Baroness Ford you said to the Select Committee a year ago that an additional £450 million might be required for conversion after the Games and you were going to go through this estimate line by line to work out exactly how much would be required. Have you reached a conclusion on that exercise?
It is just that you are making comments to us like, `It is good to go to New York because tourists spend a huge amount of money in London'. The implication is if the Mayor did not go to New York the tourists would not come to London. What actual value is that adding?
Just to slightly pursue some of the answers that we have had here. When you are planning a Mayoral visit - and, Mr Ross, you are an economist - what value do you place on a Mayoral visit, on average?
