Sydney, Jan.29 : Australian cricketing great Sir Donald Bradman will not be dropped from the line-up of citizenship questions for migrants, Prime Minister Kevin Rudd has said.

The test was introduced on October 1 by the Howard government and includes multiple choice and true-or-false questions from a pool of 200 questions.

"The Don is safe," The Age quoted Rudd as saying in response to queries about a looming selection showdown with his Immigration and Citizenship Minister Chris Evans, who wants "The Don" dropped from the test.

"I'm unaware of any plans on our part to give "The Don" the axe - I'm not lining up in that camp," Rudd told the Seven Network today.

Mr Evans is expected to commission a review of the test today, to be conducted in April, only six months after it was introduced.

Labor reportedly believes former prime minister and self-confessed cricket tragic John Howard wrote the question that asks prospective citizens to name Australia's greatest cricketer of the 1930s.

The answer provides a choice between Sir Donald Bradman, (cyclist) Sir Hubert Opperman and (billiards player) Walter Lindrum.

"I think it is a symbol that perhaps there has been some political interference in the setting of the test and its questions," Evans told ABC radio today.

"We want to make sure the test is appropriate and that it is based on what people really need to know in order to become citizens of the country ... not necessarily the historical facts about some of our past sportsmen."

Rudd said the test's review is about making sure it is heading in the right direction.

The majority of newcomers are passing the much-criticised test and it has an overall pass rate of 93 percent, results show.
