Islamabad: Former Pakistani president Pervez Musharraf has termed ex-prime minister Nawaz Sharif a "compulsive liar", a media report said.
In an interview with ARY channel, Musharraf said Sharif was suffering from "paranoia" and that was why he "speaks against me day and night".
"He (Sharif) is a compulsive liar," the former military ruler was quoted as saying by the Gulf News.
Musharraf toppled Sharif`s government and seized power in October 1999 in a bloodless coup. He later sent the prime minister into exile to Saudi Arabia.
As prime minister, Sharif had agreed to a "sell out" on the Kashmir issue during the Lahore visit in February 1999 by then Indian prime minister Atal Behari Vajpayee, Musharraf said.
He criticised Sharif for taking credit for the nuclear tests conducted by Pakistan in May 1998 in a response to similar tests by India.
"Nawaz Sharif was against conducting the tests but agreed under pressure from others," Musharraf said.
The former president has now been living in self-imposed exile in London since leaving Pakistan in 2008. He has also formed a political party - the All Pakistan Muslim League.
