The Pakistan Cricket Board's (PCB) disciplinary committee has been asked to investigate an alleged violation of the code of conduct by Latif, PCB chief executive Ramiz Raja told Reuters on Sunday.

The 35-year old wicketkeeper criticised PCB selection policies on a private television channel last week after he was overlooked for the one-day series against New Zealand.

"He is under our contractual obligation until December 24 and is not allowed to criticise the Board or its policies," Ramiz said.

"Even otherwise, he is a former captain and is expected to behave in a dignified manner and not embarrass Pakistan cricket. If he has grievances he should have discussed them with us instead of going on air with them," Ramiz added.

Latif stepped down as captain before the recent series against South Africa.

"I have accepted in my reply that I have violated the code of conduct," said Latif, who has played 37 Tests and 166 one-day internationals.

Latif has been in trouble with cricket authorities before.

Last August, he was pardoned by the PCB after apologising for writing a letter directly to the International Cricket Council (ICC) on match-fixing.

He was left out of the Pakistan team for three years from 1998 after his role in exposing the match-fixing scandal in the country.
