PTI  chairman Imran Khan said on Tuesday that any PTI legislator who opposes the bill has no place in his party.

Imran tweeted  that the COI bill is part of PTI's commitment to the nation and he will take strict action against the party's KP legislators who are opposing or trying to delay the passage of bill in the provincial assembly.

Comment:

If the PTI have made a commitment to the people then they must honor that promise by supporting the Whistle blower protection & vigilance commission  Bill

Many Nations across the globe do this already , with various witness protection schemes.
