The documents were leaked as Sharma had an 'intimate relationship' with Shivani, which had developed soon after he joined the PMO in 1997, the sources said citing the charge sheet whose contents have remained behind a veil of secrecy so far.
On the relationship between the two, the charge sheet mentions that it was 'so intimate' that Sharma spent several nights with Shivani at her residence in east Delhi.
As evidence, the police have cited statements of Sharma's official driver Rajiv Vaidh and entries in the log books of his official vehicle.
Sharma started ignoring Shivani after she gave birth to a son in December 1998 prompting her to blackmail him, the charge sheet says.
