Melbourne, July. 30 (PTI): Under fire for cancelling Indian doctor Mohammed Haneef's visa on character ground, Australian Immigration Minister Kevin Andrews is expected to make public some of the secret information based on which he took the decision.

Andrews is still seeking legal advice on whether he can release the information, but it is believed that his office is optimistic and will make it public within 24 hours, SKY news channel reported today.

However, as more ministerial mistakes emerge, there were increasing calls for the minister not only to apologise, but to resign as well.

Haneef's lawyer Peter Russo, who had accompanied him to India, also joined the line of lawyers and public interest advocates to release the secret information he used to cancel Haneef's visa.

"Because it's gone on for quite some time, and he's saying that he was briefed with the material that made him come to that decision, and yet that material remained secret," he was quoted saying by the ABC News.

Andrews, on Saturday, said Mohamed Haneef had no choice but to return to India.

"I have indicated that the Commonwealth has no objection to Haneef leaving, indeed the effect of the visa cancellation is that he should remove himself, he should depart Australia in any event," he said.

But yesterday, the fact Haneef did leave the country so swiftly was being cast by the minister as a sign of guilt.

In the same interview, Andrews also wrongly claimed that Haneef's baby had born a month before his arrest.

Andrews said he made an inadvertent error, however the continuing mistakes and doubts about the quality of the evidence used to cancel the visa may mean the public trial of Andrews was well under way.
