Hollywood actor John Cusack is the latest supporter to visit WikiLeaks founder Julian Assange in his continued stay at the Ecuadorian Embassy.

The American star joined US activist Daniel Ellsberg and Indian-born author and activist Arundhati Roy for a meeting inside the embassy in London.

WikiLeaks said the three were marking the fourth anniversary of Assange being in “detention” without charge, as well as commenting on the round-the-clock police presence outside the embassy.

The Australian has been granted political asylum by Ecuador but faces arrest if he leaves the embassy. He is wanted for questioning in Sweden over allegations of sex offences – which he denies – but fears he will be transferred to the US to be grilled over the activities of WikiLeaks.
