I have had a lot of discussions with both of them about this issue, but since the hon. Gentleman is an expert on the subject he will know that what really matters is the real effective exchange rate. We have devalued substantially against the dollar, by more than 10%, and that must be put into the mix. One lesson we learned from the 2008 financial crisis, when we had sterling devaluation of 25%, is that that does not automatically translate into improved trade.
