Dr LEIGH (Fenner) (14:51): My question is to the Minister— Mr Pyne interjecting— Mr Joyce interjecting— The SPEAKER: The Leader of the House will cease interjecting. The member for Fenner will just take a seat somewhere there for a second. The Deputy Prime Minister and the Leader of the House are preventing me hearing the question. The member for Fenner can begin again. Dr LEIGH: Thank you, Mr Speaker. My question is to the Minister for Revenue and Financial Services. Why won't the government join with the opposition to produce a package of superannuation concession reforms that will add $4.4 billion to the budget bottom line over the medium term?
