A hidden microphone has been found inside the Ecuadorian embassy in London where WikiLeaks founder Julian Assange has been living for the past year, the country’s foreign minister has said.

Ricardo Patino said the microphone was found inside the office of the Ecuadorian ambassador to the UK, Ana Alban, in Knightsbridge in central London.

The foreign minister did not say who was believed to be responsible, and the embassy made no comment today – Mr Assange’s 42nd birthday.

Mr Patino said the device was discovered during a brief visit he made to London last month when he met Assange and held talks with British Foreign Secretary William Hague.

‘We regret to inform you that in our embassy in London we have found a hidden microphone,’ Mr Patino told a news conference in the Ecuadorian capital Quito.

‘I didn’t report this at the time because we didn’t want the theme of our visit to London to be confused with this matter. Mr Patino added: ‘Furthermore, we first wanted to ascertain with precision what could be the origin of this interception device in the office of our ambassador. ‘We are sorry to say so, but this is another instance of a loss of ethics at the international in relations between governments.’
