Thanks for that update. Sky News just had a breaking story 15 minutes ago about the consular access, but they did not say that the servicewoman would NOT be released as was previously hinted at.
What happened was an Iranian spokesman stated that she might be released soon and then all the leftist progresso mullah-but-kissing media outlets the world over ran with, 'Iranians set to release the female sailor'.
If Britain gives into Iranian demands and states they were in Iranian waters there is no guarantee that all the sailors will be released. Iran needs to demonstrate good faith by releasing 1 of the hostages. Preferably the female.
Where they initially were is more or less immaterial to where they are being held now. Heck, we have Mexican soldiers cross our borders all the time. They never even get stopped.
