Ecuadorian Foreign Minister Ricardo Patino Aroca has said that a hidden listening device was found in his country's embassy in London during his visit to the UK last month.

At Tuesday's press conference in the capital Quito, minister Patino said that the hidden listening device was found during a regular security check by the Ecuadorian intelligence for the Ecuadorian embassy in the UK on June 16.

The microphone was found in the office of the ambassador Ana Alban.

"We immediately conducted an investigation to find the source and I will release our result at tomorrow's press conference including the source of the device, who was using it and which department installed it", Patino told.
