OK I'll go and face a trial on one thing

What trial? He hasn't been charged with anything.

Why the hell would anyone expect that to feasibly happen?

Maybe because it is fucking happening.

"SWEDISH PROSECUTORS HAVE offered to question WikiLeaks founder Julian Assange in London over rape allegations" [Mar 13, 2015]

Gee I wonder why, police trying to arrest someone defying their highest courts after losing in a fair trial.

Do they normally spend over £10 million on it? There's a big difference between the police trying to arrest someone and threatening to raid a goddamn embassy. That's completely unprecedented. You know that if this was just a normal bloke and not the founder of WikiLeaks, then they wouldn't have threatened to raid an embassy.

you're simply factually wrong about him only being wanted for questioning

Source? Because literally the first line on the wikipedia page is

Julian Assange v Swedish Prosecution Authority is the set of legal proceedings in the United Kingdom concerning the requested extradition of Julian Assange to Sweden to further a 'preliminary investigation'

Preliminary Investigation. They just want him for questioning. He has not be charged with anything.

And while you're at it, try and explain away these points - http://govwaste.co.uk/#sweden

Finally, no matter how you feel about Assange, this point is hard to argue against:

Why should this continue to be the UK's problem? This is a stalemate, and the UK taxpayer is paying the price. Send Assange to Ecuador. Let Sweden and the USA deal with Ecuador.
