Probably good - but if he has left forever.
He is already indicted in the nab court and his trial will go on in his absence and hopefully nab court will give verdict.
However bitter it is seems, maybe if zardari also goes away , while his numerous cases are under normal trial and he will definitely be sentenced, is not a so bad idea. That will help to get rid of PPP in Sind in 2023.
Ex-president and ex-pm have an exclusive advantage, and also the courts will do all to linger their cases and help them.
Maybe it is better if PTI avoid stigma of ex-pm. ex-pres under trial - than both become convicted, bhagora and vilified..
