My opinion remains the same as always on this - there shouldn't be sky-high court costs because the plain situation is that she was a British kid, radicalised in Britain, and thus she is Britain's responsibility. The refusal to acknowledge that is shirking responsibility and is purely political: there are far more dangerous individuals than Begum in the UK who they aren't even attempting to deport. This is high profile, and thus huge PR. Simple as that. Just sheer arrogance to say "we don't want her so some other country can deal with her". She should have been in the UK, in a UK prison, from day 1.
