Well I'm not too up on current events in British government, but the most recent example I know of was when a Royal Edict was used to displace some 2,000 natives of the Chagos Archipelago from their homes on Diego Rivera Island and relocate them en masse to a makeshift shantytown on the Island of Mauritius some 1500 miles away, where large numbers of them succumbed to prolonged disease and starvation. Parliament voted to leave the inhabitants where they were and the Queen signed an edict to override their vote.
The reason for this mass deportation? To clear the island for the construction of a US Naval base, ironically named "Camp Justice."
Since this gross civil rights violation occurred, the UK and US governments continue to deny any wrongdoing in the affair, and the dispatriate citizens of Diego Rivera Island have been repeatedly denied any form of retribution or compensation.
There was an excellent documentary made in 2004 about this incident, titled "Stealing A Nation." You can read about it here:

I believe they have the documentary available for BT download on

Watch the docu. I agree, it is quite amazing, though I can think of a few other adjectives that might be more apt.
