Whenever there is news of an air crash, or something happening on a cruise ship, or any other terrible disaster, the News will report that "there were 5 Britons aboard" or "on which there were no Britons".
People are people.
People died or suffered in some way. Why should it matter whether they were British or not? (and let's not get into the discussion about what constitutes 'British' or we'll be here all night).
It's as if the British press think that the world consists of Important British People and Everyone Else (of lesser importance). Are we supposed to feel more sorry if Britons were killed? or think "Oh, that's ok then" if none were?
Do other countries do the same or is it us?
