The Coalition says it is prepared to give Prime Minister Julia Gillard the benefit of the doubt over claims she was involved with the mortgage on a property partly paid for with stolen union funds but says it is time she finally gave a ''candid explanation''.
The Opposition Leader Tony Abbott on Saturday said the coalition would use the last parliamentary sitting week of the year to grill Ms Gillard over her integrity as a Slater & Gordon solicitor in the 1990s.
''The claims are coming from many sources. These questions are coming from many sources,'' Mr Abbott said.
''I am prepared to give her the benefit of the doubt but in order to give her the benefit of the doubt we've got to hear her side of the story.''
As Fairfax revealed online on Thursday, Ms Gillard told her law firm partners at Slater & Gordon in 1995 she knew nothing about the mortgage on a Fitzroy property, bought partly with union money stolen by her former boyfriend, despite having been involved in the mortgage arrangements for the property two years earlier.
A 1993 bank letter confirms that Ms Gillard - then a salaried partner with law firm Slater & Gordon - received an insurance certificate of currency, which was required for approval of a $150,000 mortgage provided by the firm's loan department.
Ms Gillard on Friday said the new claims were part of a smear campaign and the allegations ''boiled down to nothing''.
Mr Abbott said that Ms Gillard was just stonewalling and she must give a proper explanation now these new claims had come to light. The Deputy Opposition Leader, Julie Bishop, is set to lead the inquisition into Ms Gillard in parliament.
''We've asked questions in the parliament before, we will continue to ask questions in the parliament but look there are a lot of things we will be interested in doing in the parliament next week,'' Mr Abbott said.
Among the ''other things'' will be an attempt by the coalition to have temporary protection visas for refugees reintroduced.
Opposition immigration spokesman Scott Morrison will introduce a private members bill re-establishing the visas that were abolished by the federal Labor government in 2008.
Mr Abbott said the temporary protection visas will only last until it is safe for people to go back to where they came from.
''We must keep control of our borders,'' Mr Abbott said. ''We must deny people smugglers a product to sell and the best way ensure that the people smugglers don't have a product to sell is to deny them the ultimate prize of permanent residency and Australian citizenship.''
Mr Morrison said that under his bill, asylum seekers who are found to have passed through another country on their way to Australia where their applications could have been assessed will have their application for a permanent visa denied.
This would hopefully stop asylum seekers ''country shopping'' he said.
''It is a key element of the tool box which this government removed and we want to put it back on the tool box,'' Mr Morrison said.
''We call on the government to support it.''
