WikiLeaks founder Julian Assange has refused to comply with a police request to surrender himself to officers.
Mr Assange says he will remain inside the Embassy of Ecuador while his application for political asylum is processed.
The 40-year-old has been inside the Embassy in London since last week seeking political asylum.
It is part of his bid to avoid extradition to Sweden, where he is wanted for questioning about alleged sex offences.
He was served with a letter from the Metropolitan Police requesting that he surrender himself to Belgravia police station at 11.30am.
In a statement read out on his behalf, Mr Assange said he had been advised that he should decline to comply with the police request.
He added: "This should not be considered any sign of disrespect. Under both international and domestic UK law asylum assessments take priority over extradition claims."
