Who leaked the audio conversation between Buhari and Jonathan ? The Probe begins....

Indications emerged on Friday that the Presidency has begun a probe of the leakage of the telephone conversation between President Goodluck Jonathan and Gen. Muhammadu Buhari (retd.) on Tues­day March 31st.
President Jonathan had at 5.15 pm, called Buhari, winner of last Saturday’s presidential polls on the plat­form of the All Progressives Congress (APC), to concede defeat and congratulate him.

However, two days after the call, an audio file of the conversation found its way to the public domain in what a presidency source described as serious security breach.
The source, who pleaded anonymity while confirming the probe, said the action has caused the seat of power serious em­barrassment.
The source explained that the probe is to ascertain whether the recording was leaked from the presidency or was made public from Buhari’s camp.
