Why don't we deport Abu Qatada to Belgium ?

The Abu Qatada case rumbles on interminably. One of the odd aspects I've read is the fact that he is apparently wanted on a warrant from other countries such as the US, Germany and Belgium. Now, it seems the problem with deporting him to Jordan is that he may be up against a trial with witnesses against him that MAY have been tortured.

But if there is a warrant against him from Belgium why don't we just send him there ? I presume the ECHR doesn't think they torture witnesses. I've looked on the web for the possible reasons for this but apart from conspiracy theorists types saying that a trial there as opposed to one in the UK would bring out stuff that our security services might not like, can't find anything to solve the mystery.

I am not a lawyer, so this is mystifying me quite a lot, is there any one out there with more knowledge who can shed light on this issue ?
