It is very sad that the Chagossians are reported to have "exploded with joy" at this finding - because it is just "advisory" which I assume means those involved can simply ignore it.
Mauritius was, in effect, forced to hand over the Chagos Islands as a condition of being granted independence from the British. My understanding is that any such arrangement should have been made with the full and willing consent of the inhabitants. This clearly was not the case as they were forcibly removed.
It's absolutely disgusting and I don't see criticismof such an act as "Britain-bashing". I would imagine the vast majority of people in Britain - both then and now - had, and still have, little knowledge of this event because it received hardly any coverage.
For those who would like to see the reality of what happened, here is a link for a John Pilger Granada Television documentary "Stealing a Nation" which sets out in detail exactly what happened to the Chagossians. It is a truly appalling and distressing account. From the original black and white footage you will see the confused and unhappy faces of people forcibly herded onto a ship and transported, firstly to the Seychelles where they were "marched up a hill" and placed in a prison before being sent to Mauritius - then a quite poor country - where they were not properly housed or supported.
As a Labour supporter I am very upset that this event occurred during the term of a British Labour government. When Healey was asked to comment about his role in it, he replied that he "had no memory of this".
If you feel that too much fuss is being made about this event, I urge you to take the time to watch this documentary so that you can see the reality of what happened.
