Hi is suing for breach of human rights as they have changed the rules in the embassy and he is very nearly in solitary confinement. Wether you support him or not as an individual, this is not OK to do with someone you have offered sanctuary to. If they no longer wish to house him they should deal with that in an open way, not use psychological warfare to break an individual. The embassy created this bit of the situation in the first place, so brought this on themselves.
The embassy has changed the rules for housing him - his internet connection was removed totally for some time, he is no longer permitted to make political statements of any kind (removal of freedom of speech), his contact with anyone outside of the embassy is restricted - visitors have to be acceptable to the embassy and they have to give 3 day notice of any visit. Also they have to give all their personal phone numbers, facebook pages and other personal details to the embassy, which is an excessive personal intrusion. The embassy is removing all sorts of other support as well.
If they are having to tell him to clean the place up and care for the cat, I suspect he is suffering from severe depression.
He is stuck with high level personal freedom restrictions and does not have the rights of prisoners in jail. At this point, he has never been found guilty of any crime by a court of law, so is still legally innocent.
I wish the UK had negotiated this situation better, shipped him off to another country under diplomatic protection so we could maintain our general stance against death penalty etc and got the UK out of this once the Dutch decided not to pursue the situation. I think the Dutch could have handled things better too.
I think of all the money wasted on this for years and years and the police time, which could all be going to better use.
