Mr. Nicholas Tarrant:

We cannot give a blanket answer on something like this. There are complex issues with such a big step change in development. We are looking at solutions. We are happy to talk about it separately in more detail. It is not easy to be able to say that it will be exactly six, eight or nine months. Mr. Rossiter has given a good sense of the timeline for just the transformers, never mind the wider step change in development for something like 7,000 units.
