Professor Karina Butler:

We are hoping that the information from the UK will come on 22 or 23 April. We are looking at other evidence but we must bear in mind that there will be chops and changes along the way. There have been many turns. It would be wrong to have just one fixed course that does not flex with the evidence as it comes out. That causes uncertainty and living with uncertainty is hard. All of us would like a black and white answer to go forward and just do this. That would make it much easier for all of us but it would not be the right course. We will come back with advice as soon as we are asked and have the evidence. We know it is an important issue but it will not be before that.
