QUESTIONS on whether senior Howard government officials misled Parliament about their knowledge of the torture of the Australian Mamdouh Habib will be asked when Parliament resumes this month.

Greens senator Scott Ludlam told The Sun-Herald he would raise the issue in budget estimates and ask if the government wanted to ''clarify what it has previously put on the record'' in light of the WikiLeaks revelations last week backing Mr Habib's complaint that he was tortured in Egypt.

Senator Ludlam said he was concerned that, since the secret US documents had been made public, there had been no formal response from the government.

''The most important point now is to set a precedent to ensure this cannot happen again.''
