The politicians take the stand that it is prorgative of PM to appoint or dismiss any minister. The constitution makers thought this prorogative would be used by PM judiceously in the national interset and not for personal gains.The timing of adding or removing a minister should be justified in the national interset. But promises of ministerial berths just before trust vote does not withstand such an acid test. Caesar's Wife should be above suspicion. A PM should not only be honest but also appear to be so. At one time Pranabda was so ambiteous that he foolishly put forth his canddature to PM's post after the death of Smt.Indiar Gandhi knowing fully well there was a living heir to the chair in late Rajiv Gandhi.it took years for him to come back in the reckoning, but high command may still not condsider him to be blindly loyal to Nehru Gandhi family.
