Wikileaks founder Julian Assange has been denied permission to leave the Ecuadorian embassy in London for a funeral.

Swedish prosecutors have ordered him to be detained, citing nothing in the country's legislation permits his release.

It is not clear which funeral he was requesting permission to attend.

The 45-year-old Australian computer hacker has been holed up for four years in the embassy and will stay there and miss the ceremony, according to ABC.

He is wanted for questioning over a rape allegation, which he strongly denies, after a 2010 visit to Sweden.
