UK can clear MP in citizenship mess: Labor

Federal MP Susan Lamb will be eligible to recontest her Queensland seat in a by-election likely in weeks, Labor insists.

Ms Lamb is expected to resign formally from parliament on Thursday following a ruling by the High Court that disqualified Labor senator Kathy Gallagher because of her dual citizenship status.

"Susan Lamb will be eligible. The British Home Office have said that they're able to process her paperwork without her parents' marriage certificate," deputy Labor leader Tanya Plibersek told reporters in Canberra.
