MELBOURNE (Reuters) - Tennis world No. 1 Novak Djokovic was joined in Australian immigration detention by Czech women's player Renata Voracova on Friday in a row over COVID-19 vaccines that could scupper the Serbian's shot at a record-breaking 21st Grand Slam.

Both players were being kept at the modest Park Hotel in inner-city Melbourne, where scores of asylum seekers are also housed behind grey walls and locked windows.
