Imran Khan believes Mohammad Amir should be recalled by Pakistan after serving a ban and jail time for his part in the 2010 spot-fixing scandal.
Left-arm seamer Amir was included in a 26-man training squad ahead of the upcoming tour of New Zealand after becoming eligible once again following a five-year ban.
One-day international captain Azhar Ali and opening batsman Mohammad Hafeez initially refused to join up with the squad due to the presence of Amir as they prepare to face the Black Caps.
The duo subsequently agreed to take part in the camp after holding discussions with the PCB and legendary Pakistan all-rounder turned politician Imran believes the time has come for Amir to make his comeback ahead of the ODI and Twenty20 series.
He told Pakistan's ARY channel: "A 19-year-old boy [Amir was 18 at the time] commits a mistake and then did not lie in the court, confesses his guilt and completes his punishment - he should play again.
"He has apologised to everyone so I appeal to all those who are opposing his return to stop their moves against him."
Imran added: "Criminals are running the country, so it is irrational that someone who has completed his sentence is opposed on his return."
Pakistan face the Black Caps in the first of three T20s on January 15 and then compete in a three-match ODI series.
