Ecuador has granted asylum to Wikileaks founder Julian Assange two months after he took refuge in its London embassy while fighting extradition from the UK.
It cited fears that Mr Assange's human rights might be violated.
Foreign Secretary William Hague said the UK would not allow Mr Assange safe passage out of the country.
Mr Assange took refuge at the embassy in June to avoid extradition to Sweden, where he faces questioning over assault and rape claims, which he denies.
Foreign minister Ricardo Patino accused the UK of making an "open threat" to enter its embassy to arrest Mr Assange.
Mr Assange said being granted political asylum by Ecuador was a "significant victory" and thanked staff in the Ecuadorian embassy in London.
