MR VISSER
Mr Chairman yes, I was going to direct a request to you that the witnesses be excused because as we've shown throughout, we can get hold of them it's at all necessary for them to be recalled but they do have their lives.
	I have one witness for example that has got to write exams from tomorrow onwards and he's been hoping that he might be finished but he will only be available Monday or Tuesday, we do have a few strategic problems here.
