LABOR says the Opposition's tactics of disrupting Parliament and derailing Friday sittings are to blame for the Government's not going ahead with other changes to question time.

Yesterday the Government side-stepped questions about why it had not introduced changes that two years ago it said were needed for question time, which it described as a "betrayal" of the public. These included time limits on questions and answers, creating new ways to "interrogate" ministers with extra questions and requiring ministers to answer questions directly.

The Deputy Prime Minister, Julia Gillard, yesterday made no commitment to honour the changes she called for in 2006, instead saying other reforms were made to require ministers to make more formal policy statements in Parliament and to give the Opposition more questions.

"The changes we've made have already made a difference to the way Parliament works and to the nature of the opportunities available to the Opposition," she said.

Parliament resumes today after the winter break. The minister responsible for running the House of Representatives, Anthony Albanese, said the Speaker, Harry Jenkins, was the most independent in years but the Opposition had frustrated other changes, such as the Friday sitting. It was cancelled after one day when the Liberals used a cardboard cut-out of the Prime Minister, Kevin Rudd, to ridicule it.

"Not only have the Opposition said they are not interested in reforms, they have shown they are prepared to destroy any reform of which they are not a part," he said.
