An Australian lawyer representing Julian Assange has been named on a border control list, a British newspaper reports.
Human rights legal specialist Jennifer Robinson, who is part of the WikiLeaks founder's team, said she was stopped as she attempted to board a flight to Australia in April.
"Why would I need clearance to travel to my own country? So far, I have not received a proper explanation," 31-year-old Ms Robinson told The Mail on Sunday.
Virgin Atlantic crew at London's Heathrow airport told Ms Robinson she must have "done something controversial" to be on the "inhibited person list", which WikiLeaks supporters say is a secret database operated by British and US authorities.
Both governments deny the practice.
