Hmmm. Not many...
The UK's Foreign and Commonwealth Office has created a new online service - called Locate - to encourage people to register with them about where they are going every time they travel abroad.
Use our new Locate service to tell us where you’re travelling to so our embassy and crisis staff can provide better assistance in an emergency such as a tsunami or terrorist attack.The idea behind it is obviously to give reassurance to friends and families back home that in the event of a incident, government officials will be able to help track victims more easily.
A potential problem is whether citizens will be moved enough to send details of the whereabouts to the state in the first place.
Given that there is enough fear of the Big Brother culture in the UK as it is, it seems unlikely that this will get the traction officials are be hoping for.
