I think this is all a completely farce.
He shouldn’t have been granted a bogus exemption in the first place (same rules should apply to us all). But then, having been granted, it to then change their minds because of the backlash is indefensible.
I think it’s appalling to hold him at the airport in this way. He wouldn’t have got on the plane if he’s not had his exemption and the visa, which they’re now saying were incorrect (so they shouldn’t have been issued then!!). Fault lies with the Australian authorities just as much, if not more so, than with Djokovic.
