Reham Khan, the former wife of prime minister-in-waiting Imran Khan, has “advised” Pakistan Cricket Board (PCB) Chairman Najam Sethi to be petrified as her next book will have his “qisa”.

Sethi and Reham exchanged tweets on Tuesday after a Twitter user claimed that the PCB chairman was behind Reham Khan’s first book which mainly targeted Imran Khan.

The user claimed: “Rumours circulating that two stinking rats @najamsethi and @husainhaqqani are hands and gloves with @RehamKhan1 in writing her farrago of fifty lies aka book.”

Replying to the tweet, Reham Khan wrote: “Najam Sethi was so petrified of Imran’s vendetta he stayed well away from me. He doesn’t know I am not likely to forgive either.”
