Andy Murray says Djokovic has questions to answer as players dive into visa row

There was no response from the Djokovic camp, either, following increasing attention on the positive PCR test from 16 December on which he relied to obtain a medical exemption to travel and his apparent maskless appearances in public in social media posts shortly after that date.

On Monday, Djokovic and his team of lawyers won their court hearing and successfully restored his visa when Judge Anthony Kelly found the Australian Border Force had not given the player enough time to speak with his lawyers and Tennis Australia before cancelling his visa.

As Djokovic continues his preparation, he does so with clouds seeming to multiply above his head. The Australia Border Force is investigating suggestions that Djokovic disclosed incorrect information on his Australia Travel Declaration.

However photos on social media appeared to indicate he had recently travelled from Serbia as he had posed alongside the Serbian handball player Petar Djordjic in Belgrade on Christmas Day. Djokovic has not commented and it is not clear when the image was taken.
