World number one men's tennis player Novak Djokovic has had his visa to enter Australia dramatically revoked on his arrival in Melbourne, amid a huge backlash over a vaccine exemption.
Djokovic was held in the airport for several hours before border officials announced he had not met entry rules.
He was then taken to a government detention hotel. A court will decide on his deportation on Monday.
The row is around an exemption he had to play in the Australian Open.
Tournament organisers said the Serbian player, who has said he is opposed to vaccination, had been granted medical exemption by two independent medical panels organised by Tennis Australia, the body that runs the event, and Victoria state.
