Novak Djokovic: Tennis star detained ahead of new hearing

Novak Djokovic has been detained in Australia ahead of a court hearing on Sunday that will determine whether he can stay in the country. The unvaccinated Serbian tennis star faces deportation after his visa was cancelled for a second time. The government say he is a threat to public health, but his lawyers are appealing against what they called an "irrational" judgement.

Also in the programme: Could growing awareness of climate change make a significant difference to the way we travel across borders either for business or leisure? We weigh up the pros and cons of cross-border night services.

Joining Julian Worricker to discuss these and other issues are Chitra Nagarajan, a writer and human rights activist specialising in Nigeria. And Paolo Gerbaudo, a political sociologist specialising in digital culture who teaches at the Scuola Normale Superiore University in Florence.
