Deal struck on MP citizenship disclosures

Members of the federal parliament will need to publicly disclose family history and any steps taken to renounce dual citizenships under a motion which has passed the Senate.

The federal government has agreed to Labor's request for a December 1 disclosure date and for more details to be disclosed.

It's understood the deal was negotiated on Monday morning between cabinet minister Mathias Cormann and Opposition Leader Bill Shorten, with the motion passing the upper house on voices later in the day.

Attorney-General George Brandis said after a difficult time for the federal parliament, it was time for all MPs to act with integrity.

Senator Brandis reiterated doubts over the constitutional eligibility of Labor MPs Justine Keay and Susan Lamb who were still British citizens when nominations for the 2016 election closed.

"The one political party represented in this parliament which has not adopted the appropriate course is the Australian Labor Party," Senator Brandis told parliament.

Labor Senate leader Penny Wong said the government had simply adopted the opposition's position after Malcolm Turnbull couldn't reach a deal.

"The reality is this, the prime minister has been dragged kicking and screaming to this point," Senator Wong told parliament.
