How odd that this story should present itself just days after one regarding rumours on the NYSE that GIP were considering selling their stake in Gatwick..

One could almost surmise that they were trying to increase the 'potential' value of their asset... despite the fact that as has rightly already been said this is a long way from a reality...They stand to make a lot of money anyway but they'd have made even more if they could have sold it on with planning permission for a second runway. No different from doing the same with a small house on a large plot of land. This will just have to do I suppose.
