The Act is primarily addressed to these problems, and permits the government inter alia:
1. to prevent missions from setting up offices in sensitive parts of London;
2. to deal with the problem of empty former diplomatic premises by acquiring title to them and then selling them;
3. to remove diplomatic status from premises which are being misused;
4. to retaliate in kind of an overseas government insisted that a British mission move from existing premises or withheld consent to the acquisition of new premises.
UPDATE: Just a couple of minutes ago and after a long presser, Ecuador's Foreign Minister Ricardo Patiño announced that his country would grant asylum to Julian Assange. The main argument for the granting of asylum is that neither the UK nor Sweden would provide guarantees that Assange would not be extradited to the USA to face charges that carry the death penalty there.
