WikiLeaks founder Julian Assange is to take legal action against the government of Ecuador, accusing it of violating his "fundamental rights and freedoms".

The move comes several months after Ecuador cut off communications for Mr Assange, who has been living inside the country's embassy in London for over six years.

WikiLeaks lawyer Baltasar Garzon has arrived in Ecuador to begin the case, which is set to be heard in a domestic court next week.

WikiLeaks said Ecuador had threatened to remove the protection Mr Assange has had since being granted political asylum, and added that his access to the outside world had been "summarily cut off".
