Well, I can think of one fairly high-profile resident of Camden whose property has been purchased, not because it is needed for the construction of the railway but because the level of disruption in the area just in front of his particular house would be unacceptable. So there have been cases where we have purchased properties when the construction intensity would have made them uninhabitable in the long term. However, when there are peaks in construction or particularly noisy activities are taking place, there is the option to offer paid accommodation during that peak construction period, and if necessary we will use that power.
