Mr. John Tierney:

Underperformance would be catered for in the same way as in any other company - that is, by way of the employee relations element. On the delivery aspect, as Mr Barry mentioned, that is tied into the business plan, and every single activity in that plan is with a view to driving the benefits we talked about last night that will be delivered over the period to 2021 initially. As Mr. Barry described, it is from top to bottom.
