Lambie keeps her heart for the Senate

Former senator Jacqui Lambie has ruled out making a run for the federal lower house should a Labor MP resign over dual citizenship.

The Turnbull government wants Justine Keay to stand down over her British ancestry after the High Court ruled ACT senator Katy Gallagher ineligible to stay in parliament.

"Jacquie Lambie took the hard decision personally but her calling is to return to the Senate," her spokesman Glynn Williams said in a statement on Wednesday.
