And as long as there's demand for cash, it's our responsibility at the Bank of England to produce notes that are of the highest quality, notes that are cleaner, safer, stronger, and that's what we have today.
Based on the Canadian experience this will last in minus 40. As we can see today, it will last in plus 33 degree weather, and it can survive a dip in curry at my favorite White Cross shop.
