"Delegates, I hope you will understand that I don't believe it would be appropriate to carry on with the speech I was going to give you today.
"I know I have issued copies of the speech, we will make sure all delegates get copies of the speech but I think inappropriate to give that speech now, here.
"I will obviously want to carry on the discussion we have had about this issues that concern us.
"I will now return to London and once again I thank you for your indulgence here.
"I am very, very sorry it has worked out the way it has but I know that you would want to join with me in offering our deepest sympathy to the American people and our absolute shock and outrage at what has happened."
